Call for Availability

Combination humidity and temperature transmitter. Duct mount or outside air models. Choice of 2%, 3% or 5% accuracies. Polymer capacitance humidity sensor for 0-100% RH. Solid state band gap, thermistor, or RTD sensor for temperature ranges -40° to 140° F. Choice of 4-20 mA, 0-5V or 0-10V RH outputs, 4-20 mA, 0-5V or 0-10V, thermistor or RTD outputs for temperature. NEMA 4X/IP66 polycarbonate enclosure.

Typically used for air economizers, outdoor temperature and relative humidity reference, and pool room humidity monitoring. By combining a voltage or current humidity transmitter output with a passive thermistor or RTD output, the Dwyer RHP reduces instrumentation and installation costs.
