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

Installation
General Information
The RH Room transmitter is a Relative Humidity
transmitter that can be powered with either an AC or
DC supply voltage. The transmitter can also include an
optional temperature sensor for monitoring the space
temperature.
All units are shipped from the factory set up with a 4-20
mA output. The RH Room transmitter is eld selectable
with a 4-20 mA, 0-5 VDC, or 0-10 VDC output signal
that is equivalent to 0 to 100% RH.
Mounting Instructi ons
Separate the cover from the base. Attach the base
directly to the wall or to a standard 2” x 4” junction box.
Refer to the wiring instructions to make necessary
connections. After wiring, attach the cover to the base
by snapping the top of the cover on rst and then the
bottom.
