Overview

The HygroPro moisture transmitter, from Panametrics, is a loop-powered, intrinsically safe transmitter suitable for use in rugged industrial applications. When installed with proper protection, the HygroPro has certified intrinsically safe electronics in an IP67 housing.

The HygroPro benefits from an integrated backlit display which allows the use to view three parameters simultaneously. The display combined with the six-button keypad allow easy navigation of the software for configuration and diagnostics.
