3.4 Conductivity Electrode Information

The Salt 6 salinity hand-held meter is supplied with a
electrode with a BNC connector. This electrode (Order
Part Number: EC-CONSEN91B/ 35606-55) comes with
Stainless Steel rings, cell constant of K = 1.0, and a built­in temperature sensor for Automatic Temperature
Compensation (ATC). Its specially designed Ultem-body
housing has good chemical resistant properties. It
provides fast temperature response and reduces air
entrapment, which makes it easy to obtain accurate,
stable readings.

The probe materials used which have good chemical
durability include:

1. Polyetherimide (Ultem) – protective probe guard

2. Polybutylterphalate (Valox) – sensor housing

3. Stainless Steel (SS 304) – 2 steel bands

6

Instruction Manual Salt 6

Proper use of probe is essential to ensure
that the optimum measurement is taken in
a short time.

The removable protective plastic probe
guard is meant for simple periodic
maintenance and it must be kept in tact
during measurement and calibration.

Always immerse the probe beyond upper
steel band.

NOTE:

1) DO NOT remove the protective probe guard during measurement
and calibration as it may affect your readings.

2) We recommend that you do not submerge the probe above the
protective guard. You can submerge the cable for brief periods of
time, but not continuously.

See Section 7 - Probe Care and Maintenance” for more information.

Instruction Manual Salt 6

3.5 Connecting the Probe to Meter

1) To connect electrode into meter, align the connector slots with the
posts of meter’s socket and rotate connector clockwise until it locks.

2) To remove, simply rotate the connector in anti-clockwise direction
until it unlocks, and slide the connector off the socket.

3) Insert the mini phono jack of temperature sensor into the socket on
the meter as shown in Figure below.

4) Unplug the phono jack when not in use or when you want to
measure Conductivity or TDS without any temperature
compensation (Manual Temperature Compensation, see Section

5.2).

CAUTION: Do not pull or force on the probe cord or the probe

wires might disconnect.

NOTE: Keep connectors clean. Do not touch connector with

soiled hands.

4 CALIBRATION

4.1 Important Information on Meter Calibration

The Salt 6 meter has a special built-in algorithm to linearize for the
measurement of Sodium Chloride concentration. Therefore the specified
accuracies from a One-point calibration anywhere in the measurement range,
specified accuracies can be applied for the entire measurement range.

When you recalibrate your meter, the old calibration will be replaced by the new
calibration point. For example, if you previously calibrated your conductivity
meter at 2.5% and you recalibrate at 1.0, the meter will replace the old
calibration data (2.5%).

To completely recalibrate your meter, or when you use a replacement probe, it
is best to clear all calibration data. To erase all calibration data completely, see

Section 6.5 – Restore Factory Default Values.

11

Instruction Manual Salt 6

4.2 Preparing the Meter for Calibration

Before starting calibration, make sure you are in the correct measurement
mode.

Ensure that you use new Sodium Chloride standard solutions during calibration.
Do not reuse standard solutions as it may be contaminated and affect the
calibration and accuracy of measurements. Use fresh calibration solution each
time you calibrate your meter. Store solutions in a dry and cool environment if
possible.

Always rinse the probe with either deionized water or rinse solution before and
after each calibration/sample measurement to avoid cross-contamination. For

details please refer to Section 7 - Probe Care and Maintenance.

NOTE: These meters are factory set to a temperature

coefficient of 2.1% per °C.
The factory default value for normalization
temperature is 25 °C. If you need to normalize to a
value other than 25 °C, see Section 6.3 –
Normalization Temperature.

5 MEASUREMENT

The Salt 6 meter is capable of taking measurements with automatic or manual
temperature compensation.

5.1 With Automatic Temperature Compensation (ATC)

For ATC, make sure the phono jack of the probe (see Section 3.5) is securely
inserted.

The % or ppt reading displayed will be compensated for according to the

normalization temperature (20 °C or 25 °C) selected. See Section 6.3 –
Normalization Temperature.

15

Instruction Manual Salt 6

5.2 Without ATC (Manual Temperature Compensation)

For manual temperature compensation, simply unplug the probe’s phono jack
(not BNC) from the meter.

To use manual temperature compensation, you need to enter the temperature
value of your process into the meter. This is the value at which the reading will
manually temperature compensates. You can select any temperature between
0 and 50 °C. Default value is 25 °C.

1) Make sure that the phono jack (for
temperature measurement) is disconnected

C°

from the meter. See Section 3.5.

2) Switch on the meter and if necessary, press

CAL

MODE key to select temperature
measurement mode. See Section 3.7.

3) Press CAL key to start temperature
calibration process.

4) The “CA” will appear momentarily and a

5.3 Taking Measurements

To take readings:

1) Rinse the probe with de-ionized or distilled water before use to
remove any impurities adhering to the probe body. Shake or air dry.
To avoid contamination or dilution of your sample, rinse probe with a
small volume of your sample liquid.

2) Press ON to switch on meter.

3) Dip the probe into the sample.

4) Allow time for the reading to stabilize. Note the reading on the
display.

NOTE: When dipping the probe into the sample, take care to

ensure that the liquid level is above its upper steel
band. Stir the probe gently in the sample to create a
homogenous sample. See Figure in Section 3.4.

7 PROBE CARE AND MAINTENANCE

Keep the conductivity probe clean. Rinse the probe
twice, and gently swirl it while you take readings. For
best accuracy, soak a dry probe for at least 5 to 10
minutes or longer before calibration. Rinse the probe
with deionized water before storing. Never scratch the
bands with a hard substance. Do not strike the probe
against any hard surface.

Do not immerse the probe in oily solutions. Clean the
electrode thoroughly by stirring it in a mild detergent
bath or isopropyl alcohol. Wipe the probe with soft
tissue paper. Rinse thoroughly in tap water and then in
deionized water. Recalibrate the meter after cleaning
the probe.

The conductivity probe (Order Part No. EC­CONSEN91B/ 35606-55) which is included with your
meter features a removable probe guard to make
cleaning easy.

To remove probe guard:

1) Grip yellow probe guard and twist clockwise. The locking notch will
release.

2) Slide probe guard off end of probe.

NOTE: Remember to re-attach the probe guard prior to taking readings. Failure
to do so could result in erroneous readings.

12 ADDENDUM 1: CALIBRATION TIPS

You only need one calibration for measurement throughout the entire range of
the meter.

Wet the probe for 10 minutes before calibrating or taking readings to saturate
the probe surface and minimize drift. If you make measurements at extreme
temperatures, calibrate the meter at least once a week.

You should only use the conductivity probe specified for this meter. These
probes have a built-in temperature sensor. If you use a different probe without a
temperature sensor, you must measure the solution temperature separately and
manually enter the solution temperature.
