Nano PDM Series Portable Dew Point Monitor

Accuracy: ±3.6°F (±2°C) of dew point

The nano PDM portable dew point monitor is a reliable and cost effective self contained system for measuring dew point or moisture content in compressed air and gases. Compact, lightweight and easy to use, this system provides accurate, stable dew point or moisture measurements where and when you need it. With a range of -148 to +68°F (or 3000 ppmv), the ceramic hygrometer probe responds rapidly to changes in moisture content, displaying it on the LED display and transmitting it remotely via a 4 to 20 mA signal. Completely self contained within a rugged polycarbonate NEMA 4X enclosure, the monitor is fully portable - or can be easily wall mounted for permanent installations.

The nano PDM includes quick connect inlet and outlet connections for easy installation, an integral 0.3 micron filter, a flow meter and two programmable alarm relays.
