Product Details
Technical features:
1. The main indicators are better than the requirements of the regulations
2. Original three-sided observation window design and double operation hole design
3. The lifting speed is greatly improved
4. Internationally leading uniformity
5. 8 pages of test data can be provided
Functional Overview:
1. The temperature and humidity calibration box is a special test equipment used to calibrate hair temperature and humidity meters (meters), dry and wet bulb hygrometers, digital temperature and humidity meters and other types of temperature and humidity sensors.
2. The equipment realizes accurate measurement through high-precision sensors, and uses industrial programmable controllers to realize complex adjustment actions, which can realize automatic adjustment of humidity in the temperature and humidity verification box and automatic processing of humidity verification data. It has a high level of automatic control, can provide a continuous and stable humidity environment, and can meet the high-precision requirements of scientific research and measurement testing.
Factory Inspection Curve
Long peak time-temperature curve
Long peak time-humidity curve
Each device is strictly tested before leaving the factory as follows:
1. Temperature, humidity uniformity, volatility test, temperature rise and fall speed test under multiple working conditions;
2. Electrical safety and insulation test of the whole machine;
3. Verification of the accuracy of the indication, and the whole machine is aging when it is powered on;
4. Test the temperature and humidity uniformity and fluctuation of the humidity box according to the regulations, enter the file and save;
5. The indicators of each wet box have been strictly tested, and 9 temperature and humidity sensors test the fluctuation and uniformity of temperature and humidity field.
