Separated Type Environmental Test Chamber , Walk In Temperature Humidity Chamber Room
Appication :
It can also place a lot of items under test for reliability test, so as to shorten the total test time of a single product, or for products of the temperature and humidity stress screening (ESS), and need space larger dynamic test (such as printers dynamic temperature and humidity test), and bulky products are applicable to the equipment.
