Panametrics Intrinsically
Safe Monitor
Moisture Monitor Series 35IS is a
Panametrics product. Panametrics
has joined other GE high-technology
sensing businesses under a new
name_GE Industrial, Sensing.
This portable, intrinsically safe, single-channel analyzer
measures moisture in gases. Designed for portable
installations, it is used in conjunction with M Series
moisture probes for industries including:
• Petrochemical
• Industrial gas
• Furnace gas/heat treating
• Power generation
• Air dryer
• Pharmaceutical
• Aerospace
Features
• Portable hygrometers with CENELEC intrinsically safe
certification
• Displays moisture content in dew/frost point and
ppm
v
• Optional computer-enhanced response for abrupt
dry-down applications
• Available with or without built-in sampling systems
• Optional data logging capability
• M Series moisture probes
• Calibrations traceable to National Institute of
Standards and Technology (NIST)

Value Packed
The Moisture Monitor Series 35IS (MMS 35IS) is a
value-packed addition to the Moisture Series Analyzers
line. This economically priced portable analyzer has
advanced features and is certified to be intrinsically safe
to CENELEC requirements.
Advanced Moisture Probe Technology
The Moisture Monitor Series 35IS combines GE’s
technologically advanced M Series moisture probe with
state-of-the-art software and electronics for unequaled
overall performance. Measurement range is from
ambient to ppb moisture concentrations.
Optional Computer-Enhanced
Response
For use in abrupt dry-down conditions, such as
spot-sampling applications, GE computer-enhanced
response software is available for the ultimate in
measurement response speed.
Portable Configuration
The Moisture Monitor Series 35IS is available in two
battery-powered portable versions. One version is in a
damage-resistant enclosure that uses an external
moisture probe connected to the analyzer by a cable.
The other version contains a sample system inside the
analyzer enclosure that consists of a filter, moisture
probe (sold separately), isolation valves and process
connections, making it a completely self-contained
hygrometer system. Both versions are available with an
optional heavy-duty carrying case with space for
additional accessories.
NIST-Traceable Calibration
The Moisture Monitor Series 35IS is compatible with GE
M Series moisture probes. Superior sensitivity, speed of
response, calibration stability, and wide dynamic range
have made the M Series probes the standard of
performance and value in industrial moisture
measurement. They are suitable for laboratory and
industrial moisture measurement applications in gases
over a wide range of process conditions.
All moisture probe calibrations are traceable to the
National Institute of Standards and Technology (NIST).
