Product Description

335L Environmental Stress Screening Test Chambers Water-Cooled Climatic Test Chamber


The chamber used to test samples of non-heat dissipation or low heat dissipation. For test specimen with heat dissipation, the heat dissipating power can not exceed the cooling capacity of refrigeration system, otherwise it will affect the chamber temperature conversion speed and capacity. It is proposed test sample’s heat is less than 300W.
