High Low Temperature Humidity Walk In Stability Chamber with
customized Inner Size
Application:
Large volume temperature humidity stability test room is used to
test various types of materials for their tolerances of heat, cold,
dry, humidity. It is applied for quality inspection for all types
of big test samples, such as electronic products, electric
appliance, and products from communication, instrument, automobile,
plastic, metal, food, chemical, building materials, medical and
aerospace industries.
