sothermal Shock Tester manufacturer for sample placement requirements
Constant sothermal Shock Tester can be used in electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metal, food, chemical, building materials, medical, aerospace and other products with the quality of detection, is mainly used for testing the material performance under various environmental equipment and testing various materials heat-resistant, hardy properties. The thermostatic sothermal Shock Tester can be widely used in the quality testing industry of LED plastics.
1. The experimental zone is static, adhering to the power factor and effectively reducing the damage of LED products during the test.
2. The thermostatic sothermal Shock Tester is a device that simulates high temperature impact successfully, which can be programmed according to the performance of the equipment, and can effectively meet the LED test requirements.
3. Independent test space of thermostatic impact test machine can effectively meet the experiment space requirements of LED.
In order to ensure the stability and efficiency of the equipment during the use of thermostatic sothermal Shock Tester, the user should standardize the operation, including:
1, when doing environmental testing, performance of the required test sample, test conditions, test procedures and test technology, be familiar with the structure to the sothermal Shock Tester, especially for the operation and performance of the controller must be familiar with. Carefully reading test equipment operation manual, so that we can avoid the error caused by the test equipment is not normal operation that cause damage to the test samples, test data is not correct.
Proper placement of test samples. The test samples should be placed in the same plane with more than 10cm of the wall of constant temperature impact test. Sample placement should not clog the outlet and return air inlet, and the temperature and humidity sensor should be set aside. To ensure that the test temperature is correct.
3. The environmental test of the required media in the test shall be added correctly according to the test requirements. Such as hot and humid chamber water has certain requirements, test chamber water resistivity is not less than 500 euro. Meters, 10-100 general water resistivity. Meters and distilled water resistance of 100-10000. M, deionized water resistivity. 10000-100000 meters, so hot and humid test to use distilled water or deionized water with water, and be sure to use fresh, because after it is exposed to air, water are susceptible to carbon dioxide and dust pollution, the water can dissolve many kinds of material properties, in the long run, resistance rate to decline. Now some pure water is economical, and convenient, its resistivity is equivalent to distilled water.
4. The use of thermostatic sothermal Shock Tester. Constant sothermal Shock Tester with wet gauze ball (wet bulb paper) there is a requirement, not any gauze can substitute, because the reading of the relative humidity was from root is the difference between the temperature and humidity, strict said also related to the local atmospheric pressure, wind speed at the time. The temperature of the wet bulb is related to the amount of water absorbed by the gauze and the evaporation of the surface. These are directly related to the quality of gauze, so it is stipulated that wet ball gauze must be a special "wet gauze" made of linen. Otherwise, it is difficult to ensure the correctness of the temperature indicator of the wet bulb, which is the correct humidity. Wet ball of gauze was also have specific provision, gauze length: 100 mm, closely intertwined sensor probe, the probe from the humidity cup 25 to 30 mm, gauze in glass, so as to ensure the accuracy of equipment control accuracy and the humidity.
