DESCRIPTION

The Kele KHR, KHD, and KHO Series Humidity

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 transmitters are available with thermistor or RTD

temperature sensors. They come in room (KHR), duct (KHD),

and OSA (KHO) mounting styles.

FEATURES

• Calibration-free interchangeable sensors

• Twelve-point computerized calibration
