Calibration Methods of the Constant Temperature and Humidity Chamber

In actual work, the appropriate method needs to be selected according to the actual situation. Below we will explain to you several calibration methods for constant temperature and humidity chambers.


The constant temperature and humidity chamber is suitable for high and low temperature reliability tests of industrial products. The constant temperature and humidity box is used to test the parts and components of related products such as electronic electrician, automobile and motorcycle, aerospace, ship weapons, colleges and universities, scientific research units and so on. In the case of high and low temperature alternating cycles, it can be used to test its various performance indicators.


Regarding the calculation of the calibration method of the constant temperature and humidity box, we should first understand the performance and use of the constant temperature and humidity box. The constant temperature and humidity test box is the main equipment for temperature and humidity testing. Through the scientific operation test of the equipment, the temperature and humidity test is carried out on the test object, that is, the test is carried out in a specific temperature and humidity environment. The use of constant temperature and humidity chambers can effectively detect the quality and safety performance of products.


Ⅰ. Real-time measurement of constant temperature and humidity chamber


Because it can get the comprehensive environmental parameters of the test sample during the environmental test. In the test, it can be used to test products with high environmental requirements.


Ⅱ. Calibration under no-load condition of constant temperature and humidity chamber


The entire working area of the constant temperature and humidity chamber has been calibrated, and no recalibration is required when the test sample is changed, which can effectively evaluate the suitability of the constant temperature and humidity chamber.


Ⅲ. The constant temperature and humidity chamber is under the condition of zero load


The staff can calibrate the entire working area of the natural environment chamber, and can make a reasonable assessment of the acceptability of the constant temperature and humidity chamber. And after replacing the test sample, there is no need to perform calibration again.


Ⅳ. Calibration methods of constant temperature and humidity chamber


1. The measurement is carried out under no-load conditions. If there is a load, the load shall be stated in the certificate.


2. Generally, the upper limit, lower limit and center point of the equipment's use range should be selected for the measurement of temperature and humidity points, and the actual commonly used temperature and humidity points can also be selected according to user needs.


3. The location of the measuring point: when the equipment volume is less than 2m3, there are 9 temperature points and 3 humidity points; when the equipment volume is greater than 2m3, there are 15 temperature points and 4 temperature points.


Through the above technical analysis, it is not difficult to see that to judge whether the performance of a constant temperature and humidity box is qualified or not, the performance is stable and unstable, just refer to the above technical parameters.


At the same time, as a technical operator, mastering the above technical knowledge is not only conducive to the correct and scientific operation of the constant temperature and humidity test chamber, but also to the scientific maintenance of the equipment.


With the rapid development of these years, we have mature and advanced technology, experienced technical team and professional and efficient service personnel. We also have an independent R&D department, high-quality management and perfect after-sales service system. If you have any needs, please feel free to consult us.
