dew.IQ

Moisture analyzer

Features

Applications• Rack, bench, panel, and wall mount configuration

This Panametrics single-channel analyzer measuresmoisture in process gases. Designed for installation inindustrial settings, it is used in conjunction with IQ.probe
and M series moisture probes for industries including:• NEMA 4 weatherproof membrane front display/keypad• M Series or IQ.probe moisture probe compatible• Displays moisture content in dew/frost point and ppmv
• Built-in isolated current or voltage analog output• Fail-safe fault alarm relay• Two measurement alarm relays• Industrial gas• Furnace gas/heat treating• Power generation• Air dryer• Pharmaceutical• AerospaceLow cost, real-time moisture measurement
The dew.IQ is an economical, single channel, aluminum oxide
hygrometer in the IQ Series line of analyzers. It is intended forindustrial applications requiring accurate, real-time moisturemeasurement.

Intelligence simplified with IQ.probe
and M series probes
Installing the dew.IQ is highly intuitive. As a field upgrade forits predecessors, the Panametrics MMS35, System 580, Model
600 and 700 or even earlier models, the M Series probe andcable mate to the dew.IQ in minutes, minimizing installation
costs. For new installations, the IQ.probe stores its calibration
digitally, eliminating the need for shielded cable.
Both the IQ.probe and the M Series moisture probes arerugged and accurate true absolute humidity sensors withcalibration traceable to national standards. Exceptional
dynamic range, speed of response and calibration stability
have made the aluminum oxide sensor the standard for
performance and value in industrial moisture measurement
for more than 40 years.

Microprocessor-based electronics
The microprocessor-based dew.IQ accurately tracks fastchanging process conditions, and displays the moisture
content as dew/frost point temperature in °F or °C or
as ppmv with a constant pressure input on an LCD. The
measurement is also available as an analog output. Thedew.IQ features built-in isolation to ensure the integrity ofsignals to remote devices. The meter also features two Form
C alarm relays for high and low moisture limits. The large
display and six-button keypad combine to make selection ofanalog output zero and span, alarm set-points fast and easy,
and entry of calibration data simple.
