found in the gas industry. A
special model is available for
offshore use.
► Sour Gas
Corrosion-resistant materials are
used for H2S atmospheres.

The tester is ideally suited for the
measurement of the dew point of
pressurized N2, O2, H2, Ar, air, and
other bottled gases.
Bureau of Mines Model
Operation
The Chandler Bureau of Mines Dew
Point Tester is a primary instrument
used to measure the dew point
temperature of any gas. It is rugged,
portable, and can provide very
repeatable results. Because of its
primary nature, the standard dew
point tester requires no calibration.
Consequently, it is frequently
used to verify results of electronic
instruments.
The Chandler “Bureau of Minestype” Dew Point Tester consists
of a small high pressure chamber
through which the gas sample
flows. A polished mirror is at one
end of the chamber and a viewing
window at the other. The operator
controls an expandable gas through
a valve, cooling the polished mirror
until the dew point is observed. The
observed dew point temperature
and pressure may be entered into
the moisture content software
supplied with the dew point tester
to calculate the water content of the
sample. Hydrocarbon dew points in
natural gas can be obtained using
the same method.
The Chandler Dew Point Tester is
a chilled mirror device that operates
by achieving the conditions required
by the definition of dew point.
When a gas is cooled out of contact
with liquid water, the humidity or
water content remains constant,
but the percentage of saturation
increases until it reaches 100% and
moisture begins to condense. The
temperature at this point is known
as the dew point or frost point.
► Heat Treating Furnaces
Chandler instruments are easy
to use and produce reliable,
accurate answers. They have
been used for years in this
application.
The Model 13 Bureau of Mines
Dew Point Tester is a chilled
mirror device that operates
by achieving the conditions
required by the definition of dew
point.
The Chanscope II version allows lighted,
magnified viewing of the dew point with a digital
temperature display superimposed on the viewing
window in tenths of degree.

Dew Point Testers
Chanscope II Dew Point Tester
Accuracy:
±0.2°C (±0.4°F) at 40°C (104°F) to
-90°C (-130°F)
(NIST Certification Included)
Dew Point Temperature Ranges:
-29°C (-20.2°F) to ambient, with
liquid Propane
-62°C (-79.6°F) to ambient, with
liquid Carbon Dioxide
-129°C (-200.2°F) to ambient, with
optional liquid Nitrogen chiller
Chiller Devices Available:
Regular (Propane)
Quick Chiller – Can be used for Dew
Point measurements down to:
-30°C (-22°F) with Propane
-70°C (-94°F) with liquid Carbon
Dioxide
Liquid Nitrogen Chiller –
Dipstick type used for Dew Point
measurements down to:
-129°C (-200.2°F) and below with
liquid Nitrogen
-75°C (-103°F) with Dry Ice/Acetone
NOTE: The Quick Chiller and the
Liquid Nitrogen Chiller allow faster
Dew Point determinations but care
should be taken to allow components
to reach thermal equilibrium reducing
error caused by temperature
overshoot.
Ambient Temperature Range:
-20°C (-4°F) to 40°C (104°F)
Operating Pressure: Up to 5000
psig (34.6 MPa)
Optional LCD readout pressure
gauge available
Connections: Sample inlet and
outlet: 1/8” NPT; Refrigerant, 1/8”
tube
Power: Battery-powered (NiMH),
100-240VAC, 50/60 Hz, smart
charger.
Ship Weight: 25 lb (11 kg)
Carrying Case: 14” x 18” x 7”
(35.5cm x 45.7cm x 17.8cm), watertight, form-fitted resin case
Model 13 Bureau of Mines Dew
Point Tester
Accuracy: ± 0.5°F (± 0.25°C)
Dew Point Temperature Range:
Dependant on which thermometer is
chosen.
Operating Pressure: Up to 5000
psig (34.6 MPa)
Optional LCD readout pressure
gauge available
Connections: Sample inlet and
outlet: 1/8” NPT; Refrigerant, 1/8”
tube
Ship Weight: 25 lb (11 kg)
Carrying Case: 14” x 18” x 7”
(35.5cm x 45.7cm x 17.8cm)
Options
► Digital Readout
The Chanscope II version
allows lighted, magnified
viewing of the dew point with
a digital temperature display
superimposed on the viewing
window in tenths of degree.
The unit also has a button-hold
feature to retain the measured
value. The model uses accurate
platinum RTD and LED
readout to give the operator
instantaneous feedback during a
test.
► Pressure Range
Models are available in ranges of
1,000, 3,000 or 5,000 psig (7.0,
20.8, and 34.6 MPa).
► Regular Chiller
Uses liquid propane: -29°C
(-20.2°F) or liquid carbon dioxide
-62°C (-79.6°F) as a refrigerant.
Its geometry optimizes thermal
uniformity for superior control
and accurate determination.
► Quick Chiller
Uses the same expandable
gases but directs them onto
the back of the polished mirror.
Fast reaction time is achieved,
but there is an increased risk of
overshooting the dew point until
all components reach thermal
equilibrium.
► Liquid Nitrogen Chiller
Uses an immersion rod and
Dewar flask containing N2 for
temperatures down to -129°C
(-200.2°F).
► Thermometers
A wide range of thermometers
are available in Centigrade or
Fahrenheit, including certified
RTD traceable to NIST.
Thermometers are filled with a
biodegradable liquid, eliminating
the safety concerns of mercury.
