Thermal shock test chamber: Thermal shock test chamber brand Thermal shock test chamber manufacturer
The entire box is divided into three zones: the high temperature zone, the testing zone, and the low temperature zone. During the impact test, the air valves in the high and low temperature zones are automatically opened to achieve the high and low temperature impact tests.
Shelf load capacity: greater than 30 kilograms.
This system meets the reliability test specifications for cold and hot cycles
The test sample is placed on the sample rack, and a high-precision pneumatic system drives the valves in the thermal storage area or cold storage area to guide the airflow circulation, in order to achieve temperature uniformity for cold and hot testing
Adopting a special design, it saves space and is easy to operate and maintain
Two sets of adjustable stainless steel discs are attached in the testing area
Install high load-bearing pulleys at the bottom of the machine to facilitate the movement of equipment:
High tensile double-layer sealing strip that can withstand cold and heat
