3-zone temperature impact test chamber
Product description
It is used to test the degree of endurance of various materials under the continuous environment of extremely high temperature and extremely low temperature in an instant, so as to detect chemical changes or physical damage caused by thermal expansion and contraction of samples in the shortest time. Mainly used in semiconductor chips, scientific research institutions, quality inspection, new energy, optoelectronic communications, aerospace military, automotive industry, LCD display, medical and other science and technology industries.
Other name
High and low temperature (temperature) impact test chamber, three boxes (three slots) cold and hot impact test chamber, three boxes (three slots) high and low temperature impact test chamber, three boxes (three slots) temperature impact test chamber, high and low temperature impact test chamber, temperature impact test chamber。
Meet test criteria
Three-box test method: GJB 150.5-1986, MIL STD 883H, MIL STD 202G, IEC 60068-2-14, JIS C 60068-2-14, JASO D 014-4, EIA JED-2531A.。
Product features
01
Adopt the most cutting-edge electronic expansion valve technology;
02
Energy saving about 30%;
03
Continuous impact 1000 times without defrosting (optional);
04
Evaporator is not easy to frost;
05
Linear model is more convenient to realize;
06
Stable and fast temperature, better uniformity control;
07
The compressor is not easy to frost, the whole machine life is 1/3 longer than the traditional technology;
08
Non-standard design is more convenient;
09
ESS box load heating automatic adaptation;
10
Three boxes can test impact room temperature;
11
There are three parts: high temperature area, low temperature area and test area. The test product is placed in the test area, and the temperature of the high temperature area or low temperature area is rushed into the test area for impact. The test product is static; Convenient power test and impact room temperature test.
