The classification of the high and low temperature test chamber and use information

According to the test method and the industry standard, alternating high and low temperature test chamber can be divided into test and constant temperature test. Two test methods are based on high and low temperature test chamber upgrade and extend. Alternate test chamber means required high temperature and low temperature and the temperature needed for time can be set within the scope of the instrument parameters of a one-off. Test cases will follow set procedures. Do fixed temperature high and low temperature test chamber, make the test result is more close to the natural climate, simulate the worse natural climate, so as to improve the reliability of the test sample. Using high and low temperature test chamber environmental test, samples should be familiar with the performance/test procedure, test conditions and test the required test technology, the technical performance of test equipment used and equipment structure, especially the operation and performance of the controller. Should also read carefully test equipment operation manual, in order to avoid the error lead to abnormal operation of test equipment and test samples of damage caused is not the correct test data. Sample of high and low temperature test chamber placed distance chamber wall should be greater than 10 cm, multiple samples should be placed on the same plane as much as possible. Sample should not block the outlet and back to port, and a certain amount of distance for temperature and humidity sensor. Make sure you have the correct test temperature. The power of the high and low temperature test chamber consists of three phase five wire. Equipment cable for four core, three phase and a zero line. Please distinguish between neutral line. The equipment part of the load and the control system is single phase, if neutral line failure, equipment will not be able to work and be damaged. High and low temperature test chamber grounding line is equipped with a grounding line column. To ensure good grounding device can make the equipment safe and reliable. The zero line and ground connection can lead to abnormal operation of the equipment. Due to factors such as the user scene, cable need to be extended, please make sure that used to extend cable and power supply of rated parameters can meet the demand of high and low temperature test chamber. High and low temperature test chamber is absolute humidity and relative humidity of the ratio of the maximum humidity. Its value shows the saturation of water vapor. It is the unit of %. The air is saturated air relative humidity is 100%. The air relative humidity is 50%, half of the water vapor in the air at the same temperature of the saturation point. More than 100% of the water vapor in the air relative humidity will usually condensation. With the increase of temperature, the more the water contained in the air, that is, under the condition of the water vapor content is same, temperature, relative humidity is reduced. Therefore, must provide the relative humidity in the temperature data at the same time. Dew point can be calculated by relative humidity and temperature. The above explanation is the classification of the high and low temperature test chamber and use information, hope can help you, if you want to learn more about information of high and low temperature test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
