TRH-303 is a model in the TRH-300 series that can measure temperature and humidity at the same time. Through voltage or current signals, the measured temperature and humidity values are transmitted to the display panel or displayed on the back-end system. The TRH-300 series utilizes sheet-type polymer capacitors to measure temperature and relative humidity accurately. Excellent design, even moisture, dust, dirt, grease, and common chemicals will not affect its measured value.

Temperature /Humidity Transmitter TRH-303 4~20mA Output Application diagram and Instruction:
TRH-303, 4~20mA temp/humidity transmitter
Application Note:
1. One (+) power wire to Humidity or Temp (+) terminal ; Both Temp/Humidity
2. The signal would be out from the (-) terminal and connect this wire to the (+) terminal of the controller AND
3. The (-) terminal is the connected to the Ground (-) of the power source.
Our transmitter is a two wire system with the positive (+) as power source and the negative is the Communication Source.
