Constant temperature and humidity test box is also called constant temperature and humidity test machine, constant temperature and humidity test box, programmable damp heat alternating test box, constant temperature machine or constant temperature and humidity box. It is used for testing the performance of materials in various environments and testing the heat, cold, dry and humidity resistance of various materials. It is suitable for testing quality of electronic, electrical, mobile, communication, instrument, vehicle, plastic products, metal, food, chemical, building materials, medical, aerospace and other products. Standards: GB / t5170.5-2008, GB / t10586-2006, GB / t2423.1-2008 test a, GB / t2423.2-2008 test B, GB / t2423.3-2006 test Ca, GB / t2423.4-2008 test

Preparation before installation and operation of constant temperature and humidity test chamber

a) This testing machine should be away from heat source and inflammable and explosive substances.

b) The testing machine must be placed on the flat ground without corrosive gas around the well ventilated room.

c) There must be a certain gap (at least not less than 50cm) at the back of the testing machine so that the condenser in the refrigeration system can effectively dissipate heat.

d) Only when the ambient temperature is between 10 ℃ - 30 ℃ and the ambient humidity of 70rh ± 10rh, can the machine get the best and most stable operation; if the ambient temperature changes too much, the temperature and humidity control and cooling speed cannot be very stable.

e) This machine should not be exposed to direct sunlight, and maintain indoor air circulation.

f) Please avoid burials and dusty places.

g) The power supply of this testing machine is: 3 Φ, 380V, 50Hz

h) Ground wire is necessary for this test machine. The grounding wire must be properly constructed in accordance with the technical guidelines for electrical equipment.

i) Water for humidification must be prepared. Pure water or distilled water must be used for humidification, and underground water is prohibited.
