Series WHT Weather-Resistant Humidity/Temperature Transmitter

Brand: Dwyer Instruments, LLC

The compact Series WHT Humidity/Temperature Transmitter is 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. 

The transmitter is available with 4 to 20 mA or 0 to 10 VDC output signals for both temperature and humidity.

This transmitter is ideal for measuring outside air temperature and humidity levels for air handling economizer applications.
