CR3B Clean Room Monitor, remote Pressure,Temp, RH, Analog op

Description

The CR3 Series Cleanroom Monitor, was developed specifically to allow for monitoring of confined spaces with accuracy and reliability. The CR3 allows for either in-room or remote monitoring with three different models; integrated sensors, remote sensors or display only to suit a variety of installation needs. It features a flush fitting stainless-steel front plate that enables the user to wipe-down the unit when necessary.

The CR3 allows for more efficient measurement of three critical parameters; humidity, temperature and pressure, in one flush mount enclosure. It is equipped with sensors with best in class accuracies to match cleanroom requirements, and can communicate with the building automation system via Modbus, BACnet® or Analog outputs. It is powered by a standard 24 Vdc or 24 Vac power supply.
