The Telaire EHRH Humidity Transmitter is a waterproof RH sensing element and package ideally suited for high RH/harsh environment applications or where washdowns are required. It is designed for continuous monitoring of relative humidity and temperature with ±2% accuracy.

The sensor and electronics are contained in an epoxy-hardened enclosure designed for continuous service. A water-tight membrane filter is installed over the RH sensor for increased protection against high RH, contaminants, and washdowns. The EHRH withstands 100% saturation. The bulk polymer resistance sensor is impervious to most contaminants, and surface contamination such as dust does not alter accuracy. Continuous temperature compensation adjusts for temperature-induced changes, ensuring high accuracy over the entire operating range. Applications include greenhouses, textile mills, food processing, shipping containers, swimming pools, and hospital suites.
