INTRODUCTION
1.1

Performance Features

• State-of-the-art ceramic metal-oxide moisture sensor with chemically inert
materials coupled with physical resilience provides long-term reliability in
the most arduous applications. Robust construction is exceedingly durable
in liquid. Not affected by pressure shocks.
• High integrity moisture in liquid measurement from 0.01ppm
level at +20 °C (68 °F).
• Sample Analysis over temperature range 0...+50 °C maximum (32...122 °F)
• Three 4...20 mA outputs with configurable units / ranges. RS485 Modbus
RTU communication. Four built-in user-adjustable alarm contacts.
• Assured measurement accuracy with each sensor calibrated across the
entire measurement range and certified traceable to NPL (UK) and NIST
(USA).
• Certified intrinsically safe.
• Replaceable sensor element with Michell Calibration Exchange Service for
professional, scheduled and low cost recalibration to minimize downtime
and cost.
• Up to four independent measurement channels with any combination of
moisture in gas and moisture in liquid and oxygen measurement at low
per-channel cost.
• Customized sampling systems to meet even the most demanding

applications.
