2019 Good Quality Programmable Thermal Shock Test Chamber For Led Products – Thermal Shock Testing Chamber – Hongjin

The three box type cold and heat shock test box is designed and manufactured according to the requirements of the user. It is suitable for high and low temperature impact test and storage and test in high temperature or low temperature environment for the whole machine and parts of aviation, aviation, military, naval, electrical, electronic and other products. In order to evaluate the test behavior of the whole machine (or component), electrical apparatus, instrument, material, coating, coating and so on, the user will test the climate and environment accordingly.   Product features 1 The equipment is divided into three parts, which are high temperature box, low temperature box and test box. The unique structure of heat break and the effect of heat storage and cold storage are collected. The cold and hot air road switching mode will be applied to the test area to realize the purpose of the cold and heat shock test. 2 Using the most advanced measuring device, the controller adopts the man-machine interface controller of large color liquid crystal touch control dialogue LCD. It is easy to operate, easy to learn, stable and reliable. In English, complete system operation condition, 3 It can independently set the functions of three different conditions, such as high temperature, low temperature and cold and heat shock. When the cold and heat shock conditions are carried out, two slots or three grooves and cold and hot punching can be selected to carry out the function of the impact of the high and low temperature testing machine. It has fully automatic, high precision system loop, any machine parts movement, P.L.C locking process, P.I.D automatic calculation control, and high temperature control precision. Conversion method The test sample is placed in the test chamber, and the high-pressure cylinder is used to open and close the damper, and the hot and cold air is quickly blown into the test slot according to the action, thereby achieving the purpose of rapid temperature change. Balanced Temperature Control System (TBHC) + Special Design Air Supply Cycle   Material a) Inner box: SUS304 stainless steel plate. b) Outer box: Cold-rolled steel plate, pickling phosphating surface, electrostatic spray anti-rust (or stainless steel plate) c) Basket: SUS316 stainless steel plate. d) Insulation: double protection of rigid polyurethane foam + aluminum silicate insulation cotton. e) Damper seal: high and low temperature resistant silicone rubber seals.   Box door a) Test the door with a single door, open the door and open the front. b) Two high-low temperature silicone rubber sealing strips and anti-condensation electric heating device for window frame/door frame. c) With observation window W250xH320mm3 layer vacuum layer, box lamp PL lamp 11W illumination lamp.   Technical Parameters
