General Information on
pH Calibration for Orion 310
A one or two-point calibration should be performed using fresh buffers
before pH is measured. It is recommended that a two buffer calibration,
using buffers that bracket the expected sample range, be performed at the
beginning of each day to determine the slope of the electrode. This serves
the dual purpose of determining if the electrode is working properly, and
storing the slope value in memory. For maximum accuracy, perform a
one-buffer calibration every two hours to compensate for electrode drift,
using a fresh aliquot of pH 7 buffer.
When operating in the LogR mode, the meter does not require the use of a
separate ATC probe. The PerpHecT meters measure the resistance of the
pH sensing glass and converts the value to temperature-compensated pH
measurements. For optimum results, PerpHecT electrodes or PerpHecT
ROSS electrodes should be used.
For best results, it is recommended that the unit be calibrated for
temperature in the LogR mode. Alternately, an ATC probe may be used.
If LogR or an ATC probe is not used, all samples and standards should
be at the same temperature or manual temperature compensation should
be used.
Stir all buffers and samples with a magnetic stirrer while a measurement is
being made.
NOTE:
heat to change solution temperature. To avoid this,
place a piece of cardboard, foam rubber, or other
insulating material between the stir plate and
beaker.
Always use a fresh aliquot of buffer whenever calibrating.

Introduction to Patented digital
LogR pH Measurement for
Orion 310
Obtaining accurate pH values depends on both correct measurement of
standard and sample temperatures and on compensation for any variations
in these temperatures. This thermal compensation has generally been
accomplished either manually (by measuring sample solution with a
thermometer and then dialing in the measured temperature on the meter),
or automatically (by placing a separate temperature probe together with
a pH electrode in the solution).
The temperature of a solution affects pH measurements in two principal
ways:
1. The pH of buffers and samples actually changes slightly with
temperature. For buffers, this change is known and is built into
the PerpHecT series of meters.
2. The slope of the calibration, which the meter uses to convert
millivolt readings to pH, changes with temperature. At 25° C,
a 10 degree change in temperature changes the slope by 3.4%.
How important is direct temperature compensation to pH measurement?
To see the effects of temperature, look up your approximate sample
temperature on the left side of Table 1. Read across the top to your
approximate pH value. The value shown at the intersection is the error
a 1° C change in temperature will cause in pH measurement without
compensation. Accurate temperature compensation is essential to accurate
pH measurement.

A. What Is digital LogR?
PerpHecT pH meters allow for direct temperature measurement and
temperature compensation from your pH electrode. With simultaneous
measurement of pH and temperature, the patented Orion digital LogR
technology makes it possible using most standard glass pH electrodes.
The system is based on using the electrical resistance of the glass sensing
bulb as the temperature probe. The name comes from the fact that the
logarithm of the resistance of the bulb varies almost linearly with the
reciprocal of the absolute temperature (See Figure 5). Almost all common
pH glasses show a similar decrease in resistance with increasing
temperature, and can be used with other types of meters. However,
only the exact shape of the curve for Orion PerpHecT electrodes
is in the meter’s memory.
To maximize system performance and accuracy, use PerpHecT ROSS and
PerpHecT pH electrodes.

B. Orion 310 Temperature Calibration Procedure
This procedure should be performed at least once per week to ensure
accurate temperature compensation when operating in the LogR mode.
If the meter is powered down or the electrode disconnected, it is
recommended that you recalibrate the LogR temperature. See the
Appendix Section for accuracy specifications and recommended
calibration techniques.
Choose a temperature calibration range which is at least 5° C apart
depending on your expected operating range. Evenly bracket your
expected sample temperature range. A maximum 20° C range is
recommended for maximum accuracy. For example, for measurement
around 20° C calibrate at 10° C and 30° C. For temperature span greater
than 20° C, a three-point temperature calibration is recommended.
For many samples, a single-point calibration near the expected sample
temperature will yield adequate results. A constant temperature bath or
a hot plate is recommended to hold the temperature of calibrating solution.
For best results during temperature calibration, it is recommended
that pH buffer or tap water be used as the temperature calibrating solution.
Do Not Use deionized water because the conductivity is too low to obtain a
good calibration.
IMPORTANT:
When using the meter for the first
time or restarting in the LogR mode, you must
perform a LogR temperature calibration. It is
recommended that at least a two-point temperature
calibration be performed to meet optimum system
accuracy. See Appendix Section for additional
information.

General Information on
pH Calibration for Orion 320
A one or two buffer calibration should be performed using fresh buffers
before pH is measured. It is recommended that a two buffer calibration,
using buffers that bracket the expected sample range, be performed at the
beginning of each day to determine the slope of the electrode. This serves
the dual purpose of determining if the electrode is working properly and
storing the slope value in memory. For maximum accuracy, perform a
one-buffer calibration every two hours to compensate for electrode drift,
using a fresh aliquot of pH 7 buffer.
When operating in the LogR mode, the meter does not require the use of a
separate ATC probe. The PerpHecT meters measure the resistance of the
pH sensing glass and converts the value to temperature-compensated pH
measurements. For optimum results, PerpHecT electrodes or PerpHecT
ROSS electrodes should be used.
For best results, it is recommended that the unit be calibrated for
temperature in the LogR mode. Alternately, an ATC probe may be used.
If LogR or an ATC probe is not used, all samples and standards should
be at the same temperature or manual temperature compensation should
be used.
Stir all buffers and samples with a magnetic stirrer while a measurement is
being made.
NOTE:
heat to change solution temperature. To avoid this,
place a piece of cardboard, foam rubber, or other
insulating material between the stir plate and
beaker.
Always use a fresh aliquot of buffer whenever calibrating.

Introduction to Patented digital
LogR pH Measurement for
Orion 320
Obtaining accurate pH values depends on both correct measurement of
standard and sample temperatures and on compensation for any variations
in these temperatures. This thermal compensation has generally been
accomplished either manually (by measuring sample solution with a
thermometer and then dialing in the measured temperature on the meter),
or automatically (by placing a separate temperature probe together with a
pH electrode in the solution).
The temperature of a solution affects pH measurements in two principal
ways:
1. The pH of buffers and samples actually changes slightly with
temperature. For buffers, this change is known and is built into the
PerpHecT series of meters.
2. The slope of the calibration which the meter uses to convert
millivolt readings to pH, changes with temperature. At 25° C,
a 10 degree change in temperature changes the slope by 3.4%.
How important is direct temperature compensation to pH measurement?
To see the effects of temperature, look up your approximate sample
temperature on the left side of Table 1. Read across the top to your
approximate pH value. The value shown at the intersection is the error
a 1° C change in temperature will cause in pH measurement without
compensation. Accurate temperature compensation is essential to accurate
pH measurement.

A. What Is digital LogR?
PerpHecT pH meters allow for direct temperature measurement and
temperature compensation from your pH electrode. With simultaneous
measurement of pH and temperature, the patented Orion digital
LogR technology makes it possible using most standard glass pH
electrodes. The system is based on using the electrical resistance of the
glass sensing bulb as the temperature probe. The name comes from the
fact that the logarithm of the resistance of the bulb varies almost linearly
with the reciprocal of the absolute temperature (See Figure 5). Almost all
common pH glasses show a similar decrease in resistance with increasing
temperature, and can be used with other types of meters. However, only
the exact shape of the curve for Orion PerpHecT electrodes is in the
meter’s memory.
To maximize system performance and accuracy, use PerpHecT ROSS and
PerpHecT pH electrodes.

B. Orion 320 Temperature Calibration Procedure
This procedure should be performed at least once per week to ensure
accurate temperature compensation when operating in the LogR mode.
If the meter is powered down or the electrode disconnected, it is
recommended that you recalibrate the LogR temperature. See the
Appendix Section for accuracy specifications and recommended
calibration techniques.
Choose a temperature calibration range which is at least 5° C apart
depending on your expected operating range. Evenly bracket your
expected sample temperature range. A maximum 20° C range is
recommended for maximum accuracy. For example, for measurement
around 20° C calibrate at 10° C and 30° C. For temperature span
greater than 20° C, a three-point temperature calibration is recommended.
For many samples, a single-point calibration near the expected sample
temperature will yield adequate results. A constant temperature bath or
a hot plate is recommended to hold the temperature of calibrating solution.
For best results during temperature calibration, it is recommended that
pH buffer or tap water be used as the temperature calibrating solution.
Do Not Use deionized water because the conductivity is too low to
obtain a good calibration.
IMPORTANT:
When using the meter for the first
time or restarting in the LogR mode, you must perform
a LogR temperature calibration. It is recommended
that at least a two-point temperature calibration
be performed to meet optimum system accuracy.
See Appendix Section for additional information.

pH Calibration for Orion 330
A one or two buffer calibration should be performed using fresh buffers
before pH is measured. It is recommended that a two buffer calibration,
using buffers that bracket the expected sample range, be performed at the
beginning of each day to determine the slope of the electrode. This serves
the dual purpose of determining if the electrode is working properly and
storing the slope value in memory. For maximum accuracy, perform a
one-buffer calibration every two hours to compensate for electrode drift,
using a fresh aliquot of pH 7 buffer.
When operating in the LogR mode, the meter does not require the use of a
separate ATC probe. The PerpHecT meters measure the resistance of the
pH sensing glass and converts the value to temperature-compensated pH
measurements. For optimum results, PerpHecT electrodes or PerpHecT
ROSS electrodes should be used.
For best results, it is recommended that the unit be calibrated for
temperature in the LogR mode. Alternately, an ATC probe may be used.
If LogR or an ATC probe is not used, all samples and standards should
be at the same temperature or manual temperature compensation should
be used.
Stir all buffers and samples with a magnetic stirrer while a measurement
is being made.
NOTE:
heat to change solution temperature. To avoid this,
place a piece of cardboard, foam rubber, or other
insulating material between the stir plate and
beaker.
Always use a fresh aliquot of buffer whenever calibrating.
Some magnetic stirrers generate enough

Introduction to Patented digital
LogR pH Measurement for
Orion 330
Obtaining accurate pH values depends on both correct measurement of
standard and sample temperatures and on compensation for any variations
in these temperatures. This thermal compensation has generally been
accomplished either manually (by measuring sample solution with a
thermometer and then dialing in the measured temperature on the meter),
or automatically (by placing a separate temperature probe together with
a pH electrode in the solution).
The temperature of a solution affects pH measurements in two principal
ways:
1. The pH of buffers and samples actually changes slightly with
temperature. For buffers, this change is known and is built into
the PerpHecT series of meters.
2. The slope of the calibration, which the meter uses to convert
millivolt readings to pH, changes with temperature. At 25° C,
a 10 degree change in temperature changes the slope by 3.4%.
How important is direct temperature compensation to pH measurement?
To see the effects of temperature, look up your approximate sample
temperature on the left side of Table 1. Read across the top to your
approximate pH value. The value shown at the intersection is the error
a 1° C change in temperature will cause in pH measurement without
compensation. Accurate temperature compensation is essential to accurate
pH measurement.

A. What Is digital LogR?
PerpHecT pH meters allow for direct temperature measurement and
temperature compensation from your pH electrode. With simultaneous
measurement of pH and temperature, the patented Orion digital
LogR technology makes it possible using most standard glass pH
electrodes. The system is based on using the electrical resistance of the
glass sensing bulb as the temperature probe. The name comes from the
fact that the logarithm of the resistance of the bulb varies almost linearly
with the reciprocal of the absolute temperature (See Figure 5). Almost all
common pH glasses show a similar decrease in resistance with increasing
temperature, and can be used with other types of meters. However, only
the exact shape of the curve for Orion PerpHecT electrodes is in the
meter’s memory.
To maximize system performance and accuracy, use PerpHecT ROSS
and PerpHecT pH electrodes.

B. Orion 330 Temperature Calibration Procedure
This procedure should be performed at least once per week to ensure
accurate temperature compensation when operating in the LogR mode.
If the meter is powered down or the electrode disconnected, it is
recommended that you recalibrate the LogR temperature. See the
Appendix Section for accuracy specifications and recommended
calibration techniques.
Choose a temperature calibration range which is at least 5° C apart
depending on your expected operating range. Evenly bracket your
expected sample temperature range. A maximum 20° C range is
recommended for maximum accuracy. For example, for measurement
around 20° C calibrate at 10° C and 30° C. For temperature span
greater than 20° C, a three-point temperature calibration is recommended.
For many samples, a single-point calibration near the expected sample
temperature will yield adequate results. A constant temperature bath or
a hot plate is recommended to hold the temperature of calibrating solution.
For best results during temperature calibration, it is recommended that
pH buffer or tap water be used as the temperature calibrating solution.
Do Not Use deionized water because the conductivity is too low to obtain a
good calibration.
IMPORTANT:
When using the meter for the first
time or restarting in the LogR mode, you must
perform a LogR temperature calibration. It is
recommended that at least a two-point temperature
calibration be performed to meet optimum system
accuracy. See Appendix Section for additional
information.

Orion 330 Temperature Calibration Procedure (cont'd)
To perform a LogR calibration, the LogR function must first be enabled in
SETUP mode.
1. First, initiate the LogR mode using the SETUP key. When the
LogR function is enabled, the LogR annunciator will be lit.
2. Press MODE key to access LogR temperature calibration
sequence. The LogR annunciator is on and the main readout will
display “CAL”. Press the YES key tobegin the LogR temperature
calibration sequence. When the YES key has been pressed, the
last LogR calibration type (“1-PT”, “2-PT” or “3-PT”) will be
displayed in the main readout. “2-PT” is the default.
3. Use the SCROLL (▲,▼) keys to change calibration type, then
press YES key to accept. CAL will then be displayed in the
readout. The measured CAL value, based upon the last calibration,
will be displayed. When the LogR signal stabilizes, the Ready
annunciator will light up.
4. Adjust the CAL l value using the SCROLL keys. Press YES key
to accept.
5. If a two-point calibration is selected, CAL 2 will then be displayed
in the main readout. Follow steps 3 and 4 to set the second
temperature value. Follow the same steps if a three-point
calibration is selected.
6. The meter will go to pH measure mode after accepting the final
calibration value.
NOTE:
A calibration may be aborted before
accepting the final calibration point by pressing
the MODE key. This will cause the system to display
“ESC”, proceed to pH mode and retain to the
previous LogR temperature calibration data.
