Additional Information

N/A With a range of -148 to +68 ºF (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.

Built for the needs of the compressed air & gas industry

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.
