Measurement items, methods and calculations of constant temperature and humidity box The accuracy of a constant temperature and humidity box is an important method for judging a machine. How to control the temperature and humidity of the constant temperature and humidity box, what are the main considerations. Qin Zhuo introduced to us: The constant temperature and humidity box performs some essential equipments for temperature and humidity test. The quality and safety performance of the product through the constant temperature and humidity box are mainly for laying the foundation for the research of newly developed products. Analysis of the measurement items, methods, calculations, etc. of the constant temperature and humidity chamber can be seen from some definitions. include: 1. Fluctuation: Under the condition of stable constant temperature and humidity box, the center point value of the working space changes with time. 2. Uniformity: Different products to be tested have different temperature and humidity chamber tests according to different temperature and humidity differences. 3. Deviation: Within the fixed parameter range, how far is the actual maximum and minimum value tested by the constant temperature and humidity box in the working space from the standard test value 4. Characteristics of measurement: temperature and humidity deviation, temperature and humidity fluctuation and uniformity. 5. Measurement method: Under no-load conditions, the test is carried out. If the test carries a load, the load should be indicated in the instruction manual. The upper limit, lower limit and center point of the use range selected in the measurement of turbidity and humidity. But we must consider the actual temperature and humidity points that users need. Whether the performance of the constant temperature and humidity box is stable, whether the technical parameters are accurate, and whether the performance is safe and qualified can be obtained from the above technical analysis. The constant temperature and humidity box of Dongguan Qinzhuo brand is equipped with more detailed instructions and use characteristics. If you have any questions, you can always contact Qinzhuo's professionals.
