The Telaire RH / RHT Series humidity transmitters are designed for continuous monitoring of relative humidity (RH) or relative humidity and temperature (RHT) in building automation and environmental control systems. They feature very low profile sensor enclosures that are virtually unnoticeable in most installations.

Accuracy options: ±2%, ±3%, and ±5% RH (20–95% RH). For critical environments, units can be precision calibrated to 1% accuracy within a specified RH range. The RH transmitter provides a linear 4–20 mA output corresponding to 0–100% RH. The RHT transmitter provides an additional 4–20 mA output for temperature over selected standard ranges. The bulk polymer resistive sensor is impervious to most contaminants, and continuous temperature compensation ensures high accuracy over the entire operating range. Enclosure: rugged pressure-cast aluminum weatherproof housing.
