Themal Shock Chamber with Humidity

Thermal shock cycle test and dew condensation cycle test can be conducted with this chamber only.

Notebook PC, phones, auto electronics are exposed to sudden temperature changes because they are moved from outdoor to indoor and vise versa.
It is necessary to conduct thermal shock cycle test with sudden change between high and low temperatures. Also dew condensation is a big issue. The dew condensation effects performances and functions of electronics equipment causing corrosion, migration and malfunctions. The dew condensation test is important for checking these conditions. By using newly developed thermal shock chamber with humidity, you can save space and cost because only one chamber is required.
     

Features

    
New type thermal shock chamber

The high temperature chamber of standard thermal shock chamber is changed to high temperature and humidity chamber, making the dew condensation cycle test possible. Since two types of tests can be conducted with this chamber, you can save space and cost, labor for taking out and in specimens.
Thermal shock cycle test functions

Lowest low temp. exposure temp. is -70°C （TSA-101S/TSA-201S -70°C） and highest high temp. exposure temp. is +150°C （TSA-101S/TSA-201S +200°C）. They conform to testing standard such as IEC 61747-5.
*For details of testing standards, please contact us.
Equivalent functions to humidity cycle test chamber

· Uniform dew condensation with excellent temperature uniformity
· The dew drop from ceiling can be prevented by controlling temperature of test area wall.
· Air velocity variable is installed on the high temperature and humidity chamber to control dew time and dew uniformity.
· A defrost function is attached on the high temperature and humidity chamber. It is not necessary to interrupt the test for defrosting.
