Product profile: The walk-in constant temperature and humidity test chamber is widely used in aviation, aerospace, electronics, instruments, electrical products, materials, automobile parts, plastic rubber products, chemistry, building materials, medical treatment, photovoltaic and other industries. The environmental simulation reliability tests were carried out under the conditions of high temperature, low temperature, high temperature, low temperature, high temperature and low pressure, light, rain, salt spray corrosion and sand dust. The walk-in constant temperature and humidity test box can provide large parts, semi-finished products and finished products for temperature and humidity environmental testing. It is mainly composed of control panel, distribution panel, heat preservation storage board, blower, heater, humidifier and freezer. The main specifications are divided into seven standard indoor dimensions and 28 test specifications under different conditions. It adopts the combination of the storage board unit, the internal volume can be enlarged arbitrarily, easy to disassemble and assemble, the material of the storehouse board is made of stainless steel material and American steel plate baking paint material, the structure is sturdy, waterproof and beautiful.
