The difference between programmable constant temperature and humidity testing machine and walk-in constant temperature and humidity chamber

One,Programmable constant temperature and humidityTesting machineScope of application:

QuasiIt truly imitates the complex natural environment of low temperature, high temperature, high temperature and high humidity, low temperature and low humidity, and is suitable for product reliability testing in various industries such as plastics, electronics, food, clothing, vehicles, metals, chemistry, building materials, and university scientific research institutions of auto parts.

II,Varieties of programmable constant temperature and humidity testing machine

1. The constant temperature and humidity testing machine is also called the upper and lower temperature alternating humidity and heat testing machine. The difference is that the title is different, and its function, characteristics, principle, structure, use and application methods are the same.

2,Walk-inThe constant temperature and humidity room is simplylargeConstant temperature and humidity testing machine, but with the constant temperature and humidity testing machine has a lot of difference.

Three,Common points of two kinds of constant temperature and humidity test equipment

1, can be ableQuasiIt accurately imitates the complex natural environment of low temperature, high temperature, high temperature and high humidity, low temperature and low humidity to provide reliable detection for products.

2, the function, principle, characteristics are the same

Four,Constant temperature and humidity testing machine and walk-in constant temperature and humidity chamberDifference

1, scope of application: constant temperature and humidity testing machine is suitable for product sampling or relatively small volume of product reliability testing. Walk-in constant temperature and humidity chamber is suitable for batch inspection of products or reliable inspection of relatively large products.

2. Structure: The common inner box of the constant temperature and humidity testing machine is processed and formed by imported SUS304# stainless steel mirror panel. The wall surface is high temperature resistant. The outer shell is processed and formed by high-quality cold-rolled plate or SUS304# yarn grain stainless steel. Phosphating electrostatic powder spraying on the outer surface is treated at high temperature. The common inner box of the walk-in constant temperature and humidity chamber adopts SUS304# stainless steel plate, and the outer shell adopts color steel plate.

3. Appearance: The constant temperature and humidity testing machine is generally integrated, that is, the refrigeration system, heating system, wind circulation system and waterway system are all installed in the casing. The walk-in constant temperature and humidity room is generally separated from the control system. That is, the control system is generally installed outside the box.

4. Volume: The walk-in constant temperature and humidity chamber is larger than the constant temperature and humidity testing machine, and the installation space request is also larger.

5. Consumption: The walk-in constant temperature and humidity chamber has a longer consumption period than the constant temperature and humidity testing machine, and the constant temperature and humidity testing machine can be directly handed over to the customer for use after installation and debugging in the manufacturer, while the walk-in constant temperature and humidity chamber needs to be assembled and debugged at the location designated by the customer before it can be used (because the walk-in constant temperature and humidity chamber is too large to be transported and needs to be disassembled).

6. Cooling method: The constant temperature and humidity testing machine is generally air-cooled, and the walk-in type is generally water-cooled (water tower, water pump, and water pipe need to be installed)

7. Price: The walk-in constant temperature and humidity chamber is much higher than the constant temperature and humidity testing machine.

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