What is the difference between the constant temperature and humidity test chamber and the walk-in constant temperature and humidity chamber?

^{Programmable constant temperature and humidity test box}

^{Can accurately simulate low temperature, high temperature, high temperature and high humidity, low temperature and low humidity complex natural environment, suitable for plastic, electronics, food, clothing, vehicle, metal, chemical, building materials, automobile parts university research units and other industries of product reliability testing.}

^{Type of constant temperature and humidity test box}

^{1. Constant temperature and humidity test box is also called high and low temperature alternating humidity and heat test box, the difference is that the name is not the same, its function, characteristics, principle, structure, use, use method are the same.}

^{2. The walk-in constant temperature and humidity room is simply a large constant temperature and humidity test box, but there are many differences with the constant temperature and humidity test box.}

^{The common ground of two kinds of constant temperature and humidity test equipment}

^{1. It can accurately simulate low temperature, high temperature, high temperature and high humidity, low temperature and low humidity complex natural environment, to provide reliability testing for products.}

^{2. The functions, principles and characteristics are all the same.}

^{The difference between the constant temperature and humidity test box and the walk-in constant temperature and humidity room}

^{1. Scope of application: constant temperature and humidity test chamber is suitable for product sampling or volume is relatively not very large product reliability detection. Walk-in constant temperature and humidity room is suitable for batch inspection of products or reliability detection of relatively large products.}

^{2. Structure: constant temperature and humidity test box generally adopts imported SUS#304 stainless steel mirror plate processing molding, wall surface high temperature resistance, shell is made of high quality cold rolled plate processing or SUS#304 yarn stainless steel, surface phosphating electrostatic powder spraying by high temperature treatment. Walk-in constant temperature and humidity room generally adopts SUS#304 stainless steel plate, shell color steel plate.}

^{3. Appearance: constant temperature and humidity test box generally adopts integrated, that is, refrigeration system, heating system, air circulation system, waterway system are all installed in the shell, walk-in constant temperature and humidity room generally adopts box and control system separation type. That is, the control system is generally installed outside the box.}

^{4. Volume: walk-in constant temperature and humidity chamber relative constant temperature and humidity test box larger volume, installation space requirements should be relatively large.}

^{5. Production: room than the constant temperature and humidity constant temperature and humidity test chamber production cycle is long, and the constant temperature and humidity test chamber general factory installation and debugging good it can be used directly to the customer, and walk-in constant temperature and humidity chamber to the customer designated place for assembly and debugging good can use (due to the large walk-in constant temperature and humidity room generally cannot transport, Need to disassemble before transport to customer location).}

^{6. Cooling mode: constant temperature and humidity test box generally adopts air cooling, walk-in generally adopts water cooling (need to install water tower, water pump, water pipe).}

^{7. Price: the walk-in constant temperature and humidity chamber is much higher than the constant temperature and humidity test box.}

^{8. Power supply: walk-in constant temperature and humidity room is generally in the three-phase 20KW-50KW, constant temperature and humidity testing machine is much smaller.}
