Brief introduction: Three high and low temperature impact test chamber box is suitable for electronic elements of safety performance test screening tests provide reliability test, products, etc., at the same time, through this equipment test, can improve the reliability of products and product quality control. High and low temperature impact test chamber is aviation, automobile, home appliances, research in areas such as the necessary test equipment, test and determine the electrician, electronics, automotive electronics, materials and other products, in the high and low temperature test the temperature of the environment impact parameter and the performance after the change, use flexibility, suitable for schools, factories, military industry, research, etc. Features: 1. All three of the high and low temperature impact test chamber box functions controlled by computer, is a self-developed software, has the good interface, the user's operation and monitoring is more simple and intuitive, maintain function will keep you running applications in the present condition, can temporarily change the numerical procedures section, and parameters can be set up on the screen time, the refrigeration, heating and blue transfer switch, according to the set value automatically. 2. Three of the high and low temperature impact test chamber boxes of cold box, hot box control independently, the door is independent each other, enlarge the using range of test chamber (three with a box). 3. Product insulation effect can fully guarantee. 4. The test and the circulation fan, the door is blue transmission and interlock, to protect the safety of the operator, once the door is opened, the circulation fan and blue drive power supply will be cut off. Technical parameters: Temperature range: A: B - 20 ℃ ~ 200 ℃, and 40 ℃ ~ 200 ℃ C: 60 ℃ ~ 200 ℃ Temperature fluctuation: high and low greenhouse greenhouse are plus or minus 2 ℃ or less The sample area temperature fluctuations: plus or minus 0.5 ℃ or less (temperature) The sample area bearing: 20 kg Controller: import LED display (P, I, D + S, S, r.) microcomputer integrated controller Heating system: the whole system independently, nickel-chromium alloy electric heating heater Cooling system: fully enclosed air cooling way of single stage compression refrigeration, original French "taikang" closed compressor, air cooled after lap compression refrigeration way Circulation system: low noise of heat-resistant KongDiaoXing motor. Leafy type centrifugal rotor Standard configuration: three box type high and low temperature impact test chamber equipped with multi-layer heat touch cream with lighting glass Windows 1 set of 2, test leads, try wearing holes (25 and 50 mm) 1 Safety protection: leakage, short circuit, over temperature, motor overheating, compressor overpressure, overload, over current protection Temperature conversion time: from low temperature area to high or from high to low temperature area or less 15 s Temperature response time: 5 min or less (associated with thermal recovery conditions, cooling water temperature, both exposure temperature, constant temperature time, sample weight) Temperature shock methods: vertical two boxes/vertical three box method
