Johnson Controls Wall Mount Humidity Element Transmitter with Silicon Temperature Sensor
The Series humidity devices house both a humidity and a temperature sensor in a wall or duct-mount style. The humidity sensor is capable of measuring relative humidity (RH) over the entire range of 0 to 100 percent, and its all-polymer construction provides improved resistance to chemical corrosion. The truer product line delivers devices with RH accuracy of either +/-2 percent or +/-3 percent RH. Truer humidity elements produce voltage output signals proportional to measured humidity for humidity indication. made in United States. Manufactured by Johnson Controls. Truer circuitry and calibration techniques for which patent protection is pending All-polymer humidity sensor patented sensing element provides accurate and reliable humidity sensing Tested and calibrated with equipment certified to be in compliance with national
