Transmitters are speciﬁcally designed for use in HVAC/BAS

applications. These instruments measure relative humidity

from 0% to 100%. The standard two-wire, 4-20 mA output

provides low cost humidity monitoring for building control.

The RH transmitter is available with thermistor or RTD

temperature sensors or a 4-20 mA rangeable temperature

transmitter. They are available in room, duct, and OSA

mounting styles.
