Air Temperature and Humidity Sensor

OSA-3A Air Temperature and Humidity Sensor

The OSA-3A Air Temperature and Humidity Sensor adopts imported digital temperature and humidity sensor, which has been carefully calibrated during production, and the calibration data is stored in the internal memory. The relative humidity and temperature sensor has the characteristics of digital output and can be completely inter-rotated, and does not need to go through a complex calibration and calibration process. It is outstanding in measurement accuracy, linearity, repeatability, inter-rotation, and consistency. Environmental equipment matching, instrument equipment integration, general environmental testing.
