WHT-311

WHT-311 is a compact series WHT weather-resistant humidity/temperature transmitter designed to withstand the elements. A removable sintered filter protects the polymer capacitance sensor from solid objects that may come in contact with the transmitter. This transmitter is ideal for measuring outside air temperature and humidity levels for air handling economizer applications. Typical applications include air handling economizers and air environment monitoring in agriculture or livestock cultivation houses.
