air.IQMoisture AnalyzerPackaged Solution

Features

air.IQ simplifies the selection and installation of your moisture analyzer. Install the moisture probe, wire your power and outputs to the terminal strip, and connect your gas to the inlet fitting.

• Wall mounted NEMA 4X package

• Includes the analyzer display, moisture probe, interconnecting cable, and sample system

• Features the dew.IQ moisture analyzer

• Available with the IQ.probe or with the M Series moisture probe

• Sample system provides isolation, filtration, pressure and flow indication, pre-wired, and a clear door for easy viewing of all readings

Applications

The standard air.IQ package is designed for moisture measurement in any inert gas application, in industrial environments classified as safe areas, where the process gas pressure is slightly positive to a maximum of 200 psig.

Start-Up Procedure• Insert moisture probe into the sample cell

• Start with the inlet valve and the valve on rotameter fully closed

• For dew points at process pressure, slowly open the inlet valve until fully open; then crack the valve on the rotameter to get flow on scale

• For dew points at atmospheric pressure, fully open the valve on the rotameter; then crack the inlet needle valve on the rotameter to get flow on scale

Shut-Down Procedure• Slowly close the inlet needle valve

• Slowly open the valve on the rotameter until the pressure on the pressure gauge is 0 psig

• Remove the moisture probe

If all you need is a transmitter… we offer two

DewPro MMY30 and MMY31Dew Point TransmittersThe DewPro MMY30 is a loop-powered transmitter with 4 to 20 mA output. The DewPro MMY30 is specifically designed to measure dew point or ppm in gases at line pressure or atmospheric pressure.

The DewPro MMY31 measures dew point or ppmv in gases. It is a cost-effective, loop-powered dew point transmitter designed for “in-line” installation where trace moisture measurement is required.

Both use the planar aluminum oxide sensor provides excellent corrosion resistance, longer calibration stability, and quick response times.

Applications include glove boxes, environmental chambers, test chambers, and other locations where direct insertion is required.

Features

• Loop-powered, 4 to 20 mA transmitter

• Fast response planar aluminum oxide sensor

• Trouble-free indoor or outdoor mounting

• Microcontroller electronics in Type 4X/IP67 enclosure
