Overview

The Carrier Relative Humidity with Thermistor Room Series utilizes a thermoset polymer capacitive

sensing element with a factory tted hydrophobic lter to improve its moisture resistance. The sensing

elements multilayer construction also provides excellent resistance in applications where dust, dirt, oils

and common environmental chemicals are found. The RH room sensors include on board DIP switches

which allow the user to select the desired output signal and can be powered by AC or DC power

sources. Single point field calibration can be performed by using the increment and decrement

calibration DIP switches to adjust your curve up or down in +/- 0.5% increments with each toggle of the

corresponding switches. These enhancements provide increased exibility and outstanding long-term

reliability without the need to replace the sensors in the eld. There are two enclosure options in this

series which should satisfy most commercial decors. Both enclosures feature four-way airow to

minimize self-heating. Three and Five-point NIST Calibration Certificates are available and must be

ordered separately when placing your order.

Applications: Humidication, Dehumidication, Monitoring Indoor Space Humidity, Clean Rooms, Hospitals, Process

Control, Laboratories, Museums, Schools, Oice Buildings, Data Centers, ESD (Anti-Static) Control
