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

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

The outstanding accuracy over the entire range is based on very precise calibration methods and on the latest microprocessor technology. Our well-proven capacitor-element humidity sensor ensure excellent long-term stability.
