Series RHP Humidity/Temperature Transmitters

Description: The Series RHP Humidity/Temperature Transmitters are versatile devices designed to provide accurate and reliable measurements of both humidity and temperature. Featuring models with 2%, 3%, or 5% accuracy, these transmitters are suitable for various project requirements. With integral temperature sensors, the need for additional devices is reduced, simplifying installation and maintenance. An optional radiation shield protects the sensor from radiant heating effects, ensuring accurate readings even in direct sunlight. Applications include air economizers and outdoor temperature and relative humidity reference for building systems.
