Description

Our temperature compensated humidity transmitter has been designed to meet the demand of energy-care, environmental protection, including air quality control.

The capacitance element based sensor is one of the most stable sensor available and no recalibration required.

The 2-wire design provides an easy installation, decreasing cost of field wiring .

The high humidity accuracy cover full range from 0 to 100% RH,  allowing precise measurement of the humidity over the operating temperature from-40~80 Celsius. Even condensation on the sensor will not harm it.

Each transmitter is calibrated in our computer operated atmospheric simulation chamber.
