Environmental conditions required for the application of constant temperature and humidity experimen

Understanding the conditions and conditions of the constant temperature and humidity experiment box can not only meet the buyer's test request very well, but also extend the life of the high and low temperature box. Let's briefly introduce the conditions used in the constant temperature and humidity test chamber.

　　 1. Temperature: 15 ～ 30 ℃; The manufacturer recommends installing air conditioners in the laboratory where the equipment is placed, maintaining a constant temperature, and providing excellent assistance to the life of the equipment and experimental results

　　 2. Relative humidity: no more than 85%; too much humidity or a series of experimental machines with water spray nearby may cause problems such as rusting of the machine.

　　 3. Atmospheric pressure: 86 ～ 106kPa;

　　 4. There is no intense vibration around;

5. There is no direct sunlight or direct radiation from other heat sources; the condition temperature should not be too high. If the condition temperature is too high, it will have a certain impact on the compressor of the equipment including the low temperature experiment. If it is next to the window, it must be added a window Cloth to prevent direct sunlight.

　　 6. There is no strong electromagnetic field around;

　　 7. There is no high concentration of dust and corrosive substances around.

The experimental load is subject to 1/3 of the plane of the sample rack. Too many samples (1/3 of the volume) will prevent the air circulation in the box, resulting in inaccurate temperature uniformity. The experimental samples are not easy to be too large, and too large samples will prevent The air in the box circulates, resulting in an unstable constant temperature. This point should be selected when purchasing.

Muinee test equipment reminder: The constant temperature and humidity test box is used for power supply conditions. Please acknowledge that the equipment power supply is accurately connected (the equipment cable is three phase wires and one neutral wire; the ground wire box is equipped with a separate terminal) Voltage: 380 ± 10% 3 φ, Domestic power frequency: 50Hz, the equipment sent abroad depends on each country, just buy a transformer inverter. High and low temperature boxes are used for load conditions.
