Model M70XP

Moisture Monitor

Range: 0–20lbs/mmscf

The Model M70XP is designed to monitor moisture/water content in natural gas and biogas applications. A heated conductive polymer sensor is utilized to provide a linear output of moisture concentration. The M70XP also offers an integrated sample conditioning system and Auto-Zero function that zeros the sensor on a daily or other configurable schedule.
