The high and low temperature test chamber is a necessary environmental test equipment in various industries. It is mainly used to test and determine the parameters and performance of electronic electricians, materials and other products after the temperature environment of high temperature, low temperature or constant test changes. (Simple definition: test whether the product is resistant to high temperature, low temperature or constant test) At present, there are many manufacturers and various brands are mixed. For the true rights and interests of customers, Beijing Yashilin can provide authoritative measurement certification of third-party inspection agencies as an important certificate for products! When measuring, our customers should pay attention to the following items: 1. Measurement items, methods and calculations of the high and low temperature test chamber A. Measurement characteristics: temperature and humidity deviation, temperature and humidity fluctuations, temperature and humidity uniformity B. Explanation of terms: a. Uniformity: the difference between the test points (temperature and humidity) at a certain moment in the working space of the environmental test equipment in a stable state. (Simple definition: temperature difference between points) b. Fluctuation: the amount of change of the parameter of the center point of the working space with time under stable conditions of the environmental testing equipment. (Simply defined as: the beating value of a point) c. Deviation: Under the steady state of the equipment, the measured maximum value and measured minimum value of each measurement point in the working space deviate from the nominal value. C. Measurement method: 1. The measurement is carried out under no-load conditions. If there is a load, the load should be stated in the certificate. 2. The measurement of turbidity and humidity points should generally select the upper limit, lower limit and center point of the equipment's use range, and the actual commonly used temperature and humidity points can also be selected according to user needs 3. Location of measurement points: when the equipment volume is less than 2m3, there are 9 temperature points, 3 humidity points, the equipment volume is greater than 2m3, 15 temperature points, and 4 temperature points Ningbo Vinny International Trading Co., Ltd , http://www.vinnystationery.com
