Although it is intended for use in an industrial environment, the Simple Dew is a sensitive piece
of analysis equipment. Care should be taken not to drop the analyzer or to operate it in a
manner inconsistent with its intended use.
• Open all sample ports and remove all soot and/or moisture from the lines prior to attaching
the sample tubing for the first time.
• The analyzer should be stored at ambient temperature (65-80°F or 18-27°C) for at least two
hours prior to operation.
• If the unit is to be returned to SSi for service or any other reason, protect the instrument
with at least four inches of foam or other impact-absorbing material on all sides and place it
in an appropriately sized cardboard box.
• This unit is not designed to measure the dew points in corrosive gases, such as Ammonia,
, Chlorine, and HCL.

• Please read and understand this Product Manual before operating the unit.
Failure to comply with these conditions may cause damage to the unit that will not be covered
under the warranty. Super Systems Inc. is not responsible for damage to this unit caused by
disregard of these warnings, neglect, or misuse.
The Simple Dew unit was calibrated before it was shipped from Super Systems Inc. You can
begin typical operation as soon as the unit has been allowed to stabilize in a temperature
similar to the temperature in the heat treating department. This stabilization is particularly
important for units that may have been sitting overnight in a delivery vehicle in freezing

weather. Rapid temperature change can cause condensation on the sensor which will cause the
unit to temporarily display inaccurate readings.
The use of the Simple Dew is somewhat dependent upon the application. For connection to an
endothermic generator, no pump is required since the sample gas is under positive pressure. If
this instrument is to be used on a furnace or other non-positive pressure application, an
external sample pump will be required to deliver the gas to the sensor.
Be sure that the filter (mounted to the bottom of the instrument) is clean and functional, since
high accumulations of soot can hold moisture and influence the dew point measurement. It will
also prevent soot and other contaminants from entering the unit and damaging the sensor.
The optimum flow rate of the sample gas should be between 1.5 and 2.0 Standard Cubic Feet
per Hour (SCFH), although a flow rate as low as 1.0 SCFH is acceptable. If the unit is reading
less than 1.0 SCFH, verify that there are no obstructions to the flow such as a clogged sample
line or filter, or a poorly adjusted knob on the Simple Dew’s flow meter.
Heat Treat Furnace Sampling:
external pump. The sample tube from which the sample is taken out of the furnace should
extend into the furnace past the HOT face of the refractory. For accurate results, a designated
sample port should be used to extract the sample. SSi offers two versions of sample port
assemblies (part numbers 20263 and 20264) which are ideal for this purpose. If a designated
sample port is not available, then a clean “burn-off” port on a Gold Probe, an industry leading
oxygen sensor for atmosphere control, can be used. Readings taken from the burn-off port on a
probe may be artificially high due to the presence of soot in the probe sheath.
Endothermic Generator Sampling:
small restriction valve on the flow meter. A flow rate between 1.5 and 2.0 SCFH is ideal. The
sample should be taken from the endothermic gas manifold after the gas has been cooled
. Failure to do so will result in inaccurate readings and expose the sensor to potential
damage.
The main causes of damage to the Simple Dew are the ingestion of soot and the ingestion of
water. Both of these contaminants will cause erroneous readings in the short term, and cause
long-term damage to the sensor and internal components.
A gas sample must be extracted from the process using an
For applications under pressure, the flow is controlled by the
Soot / Particulate Contaminants
When taking a sample from a furnace or a generator, care should be taken to reduce the
amount of soot that enters the instrument. The filter will trap these particles, but cleaning the
sample line before attaching the Simple Dew will increase the life of the filter. Furnace ports
can be burned off by pumping air through them while hot, or by removing them from the heat
and mechanically cleaning them. Generator ports should be opened before the instrument is
attached to allow any particulate buildup to be blown out. It is also helpful to tap on the port
while it is being blown out to eject any loose particles before the instrument is attached.
If soot is allowed to collect on the dew point sensor in the instrument, it could result in higher
readings. This soot will also retain moisture than can corrode the sensor over time. The sensor

How It Works
tip can be cleaned by carefully removing it from the sample block (see Section 2.0 of the Field
Calibration instructions) and rinsing it in isopropyl alcohol. The power should be off while this is
done, and the power should remain off for at least 30 minutes after this procedure to allow all of
the alcohol to completely evaporate.
Water / Moisture Contamination
When a furnace or generator is being started up or cooled down, the resulting gases will
contain unusually high amounts of CO
. When these gases cool, moisture will precipitate out
2
and become condensation inside the sample tubing assembly. Even if the furnace or generator
is operating normally, residual moisture may still be present in the sample tube or plumbing
system. In the same way that the ports are checked for soot (see above) they should be checked
for moisture before attaching the instrument. This is especially important when taking a
sample from a generator, since the sample port is usually preceded by a significant amount of
plumbing. All traces of moisture should be eliminated before attaching the instrument. Failure
to do so will result in erroneous measurements and could result in damage to the analyzer.
The first signs of moisture in the instrument will be visible condensation collecting in the bowl
filter and an unusually high dew point. The upper range of the sensor is +80°F, so if that value
is displayed on the instrument it is probably due to the presence of moisture. If this moisture is
not removed, it will cause the sensor tip to corrode and will eventually require the sensor to be
replaced.
To remove moisture from the instrument, the filter should be removed from the instrument
(since it will probably be wet) and an inert gas such as Nitrogen or Argon should then be flowed
through the instrument for as much time as it takes to dry out. This dry-out time will depend on
the amount of moisture present in the instrument. The condition of the sensor can be
monitored by periodically reading the dew point from the display and watching the value
decrease over time. To test if it is operating properly, verify the ambient dew point against a
web-based weather station that will report the ambient dew point for your area. If the displayed
reading is within three degrees of the reported dew point when the instrument is taken outside,
then all of the moisture has probably been successfully removed. The wet filter and sample
tubing can be re-attached after they have been completely dried out. The filter element will
regain all of its original filtering properties after it has dried out.
To prevent the possibility of moisture damaging the instrument, be sure that the measured dew
point is below ambient levels before it is stored. If necessary, Nitrogen or Argon can be used to
purge the instrument after use.
Dew point can be defined as the temperature at which the water vapor pressure of the gas
equals the saturated water vapor pressure. In other words, it is the temperature at which
condensation will just begin to occur as the gas is cooled. Dew point and relative humidity are
not the same measurement. Relative humidity is the amount of water vapor in the air compared
to the amount the air could hold if it was totally saturated, and it is expressed as a percentage,
not a temperature. To determine dew point, two main variables are required: Relative Humidity
and Temperature. The Simple Dew measures both variables to compute the dew point.

Maintenance/Safety Issues
Factory Calibration
Field Calibration
microprocessor board
The dew point sensor is a “dielectric ceramic” that varies its electrical capacitance with
changes in relative humidity. The sensor is mounted in a short probe, which is installed in a Tfitting that allows the sample gas to flow past the sensor. The tip of this probe contains the
dielectric ceramic relative humidity (RH) sensor, as well as a built in temperature sensor to
determine its dry bulb temperature. Information from both of these sensors is used to compute
the resultant dew point.
Maintaining proper sensor temperature will prevent the premature failure of the sensor. The
operating temperature of the sensor should remain below 130° F (54°C) at all times. To
determine the sensor temperature, measure the voltage between pins 5(+) and 9(-) on the
microprocessor board. The voltage will be between 0 and 1VDC. Use the chart in Appendix A to
determine the temperature in °F, or use Appendix B to determine the temperature in °C. If this
temperature shows in excess of 130°F (54°C), the length of sample tubing should be increased
to allow for adequate cooling of the sample before it passes the sensor tip.
Calibration of the sensor is recommended annually. SSi’s initial calibration is performed in our
ISO/IEC 17025 certified laboratory, and includes an NIST traceable “Certificate of Calibration”.
Any calibration performed at SSi will be NIST traceable and will have documentation of ISO/IEC
17025 certification. The certificate also indicates the accuracy of the analyzer before and after
calibration. Please contact Super Systems, Inc. at (513) 772-0060 for more information
regarding this service.
It is also possible to calibrate the Simple Dew in the field, which will require one of two optional
calibration kits. One calibration kit is NIST traceable (Part No. 31425); one kit is non-traceable
(Part No. 31030). To perform this calibration, you will need a calibration kit and a voltmeter that
will allow you to measure between 0 and 1 volt DC. Since there is no display on the instrument
itself, the voltages from the sensor circuit board will have to be translated into temperature and
dew point measurements for the purpose of verifying the calibration. The instructions for doing
this are contained in this document along with reference charts to aid in the interpretation of
the voltages.
The calibration kit consists of two bottles of saturated salt solution in which each bottle
generates a precise relative humidity percentage (R.H.%) value. One bottle is 11.3% R.H., and
the other is 75.3% R.H. These two specific calibration points are already pre-programmed into
the microprocessor board.

place by the nut on the black plastic gland.
2.0 Remove the sensor probe from the sensor sampling chamber.
2.1 Loosen the black plastic gland nut and slowly slide the sensor probe out through
the airtight seal. Care must be taken when removing this sensor probe, since the tip
is very delicate and can be easily damaged if it is mishandled. Note that the probe
has white mark at the wire entry point, which must be aligned with corresponding
white mark in plastic gland when it is re-inserted in the sampling chamber.
3.0 Install the sensor probe into the 75.3% salt solution.
3.1 Slip the black sensor gland (supplied in the calibration kit) over the sensor probe
with the sensor tip protruding from the threaded end of the gland and the sensor
wires being flush with the top of the rubber o-ring in the gland. Tighten the gland
around the sensor. This does not need to be done with a wrench or other tools, but it
does need to be tight enough to prevent ambient air from contaminating the humidity
level of the sampling chamber.
3.2 Remove the cap of the 75.3% salt solution and install the sensor gland (with the
sensor) into the salt solution. To increase the life of the calibration salts, an effort
should be made to minimize the amount of time that the salt solution is exposed to
the ambient air.
4.0 Allow the sensor to reach equilibrium with the calibration salt.

4.1 Leave the sensor in the calibration salt for a minimum of eighteen (18) hours. It is
acceptable to leave the sensor in the salt solution for a longer period of time, even a
few days, if desired.
5.0 Begin the 75.3% (Span) calibration process.
5.1 After leaving the sensor in the salt for at least eighteen (18) hours, turn the unit
on (if it isn’t on already).
5.2 Simultaneously press the “75.3%” and “Calibration” buttons on the
microprocessor board.
6.0 Verify the 75.3% (Span) calibration.
6.1 Leave the sensor in the 75.3%RH calibration salt.
6.2 Record the temperature and the dew point of the sensor. Since there is no display
on the instrument, you will need to measure the voltage from the microprocessor
board and translate that into the appropriate measurement.
6.2.1 To determine the sensor temperature, measure the voltage between pins
5(+) and 9(-) on the microprocessor board. The voltage will be between 0
and 1VDC. Use the chart in Appendix A to determine the temperature in
°F, or use Appendix B to determine the temperature in °C.
6.2.2 Temporarily record the sensor temperature.
6.3 Look up this temperature in Appendix “C” (Determining the Dew Point in °F) or
Appendix “D” (Determining the Dew Point in °C). Appendix C will show the
temperature values in Fahrenheit, and Appendix D will show the temperature values
in Celsius.
6.4 Next to the appropriate sensor temperature, note the number in the
corresponding column titled “75.3%”. This will match the measured dew point,
which can be verified wherever the dew point is displayed.
7.0 After the 75.3% (Span) calibration has been completed, remove the sensor from the
calibration salt and replace the cap on the salt.
7.1 Leave the sensor probe in the gland and while the unit is still on, allow it to
achieve equilibrium at the ambient atmosphere in the room. This is accomplished by
simply leaving the sensor exposed to ambient air for between two and three minutes.
You will know when this has been accomplished when the numbers on the display
begin to stabilize.
8.0 Install the sensor probe into the 11.3% salt solution.

Returning the Unit to SSi
12.1 After the 11.3% (Zero) calibration has been completed, remove the sensor from
the calibration salt and replace the cap.
13.0 Re-assemble the unit
13.1 After the calibration process has been completed, remove the sensor probe from
the gland and return it to the sensor-sampling chamber, taking care to position it
properly. The white mark on the sensor probe should face towards the inlet tubing.
If the white mark is not visible, then it should be placed so the sample flow directly
strikes the face of the mirror on the sensor tip. In other words, the mirror should
face the incoming gas stream.
13.2 Hand-tighten the black sensor gland to prevent air from leaking out of the
sampling chamber.
14.0 Make sure that all caps are replaced on the calibration salts, and return the instrument
to service.
This analyzer contains some components that may require periodic replacement based on the
amount of use that the unit experiences and the methods in which it is used. If service on the
