Temperature and Humidity Standard Chamber is used to examine some dedicated devices like hair temperature and humidity indicator(meter),dry and wet blub temperature and humidity meter,digital temperature and humidity meter,temperature and humidity transmitter and so on.The device is accurately measured by the temperature and humidity sensor and controlled by the industrial programmable controller,which can realize the automatic adjustment of the humidity in the temperature and humidity check box.With high control and test accuracy,it provides continuous,reproducible humidity measurement for scientific research and product testing.
All technical indexes and functions of the device accord with the requirements from"JJG205-2005 Examination Regulation of Mechanical Temperature and Humidity Meter"and"JJF1564-20 16 Correction Regulation of Temperature and Humidity Standard Chamber".
Basic principle: Use one or more standard reference sensors to measure values under known temperature and humidity conditions and compare them with the output of the sensor to be calibrated. Based on the comparison results, the deviation of the sensor to be calibrated can be calculated and adjusted accordingly.
Main structure: The structure of the sensor calibration cabin includes the main body of the cabin, which is equipped with a refrigeration and heating device and a circulation fan, and is connected with heat exchange fins. The temperature and humidity standard probe is installed on the inner wall of the cabin, close to the circulation fan side. The inner chamber for calibration provides calibration operation space and is equipped with rectifiers and circulating convection air ducts. There is a sealing ring between the insulation hatch and the main body to ensure the stability of the temperature and humidity environment inside the cabin. The overall structure can meet the accuracy calibration requirements of humidity sensors.
