The constant temperature and humidity box is an environmental experiment equipment, which is suitable for various small electrical, instrument, material, etc. humidity and heat tests. This test box adopts the most reasonable structure and stable and reliable temperature control method at present. The temperature and humidity are directly displayed, the appearance is beautiful, the operation is simple, and the temperature and humidity control accuracy is high. It is an ideal equipment for constant temperature and humidity experiments.
I. Power Selection
According to the capacity and power, the constant temperature and humidity box can be divided into 220V or 380V power interfaces. If the temperature is below -40 degrees and the cabinet is above 225L, it is recommended to choose a 380V four-phase power interface. The electricity consumption is relatively stable, which is also beneficial to the life of the equipment itself;
Use environment of constant temperature and humidity box
(1) Performance guarantee Ambient temperature range: 5 ~ 35 ℃
(2) Natural drainage outlet: The drainage pipe must not have bumps in the middle, and the ground must not have too much slope.
(3) Relative humidity: not more than 85%
(4) Atmospheric pressure: 86 ～ 106Kpa
(5) No strong vibration around
(6) No direct sunlight or other heat sources
(7) The constant temperature and humidity box can set the temperature and its corresponding humidity point within a certain range.
Three, air cooling and water cooling options:
Constant temperature and humidity box is generally sufficient to use air cooling, water cooling is generally a large constant temperature and humidity chamber or large box rapid temperature rise and fall test machine, the general cold and hot shock test box is more water-cooled;
4. Size selection The size of the general constant temperature and humidity box is determined according to the size of the test product. According to the requirements of the national standard GB2423, the size of the test studio is greater than or equal to three times the test product. The effect of this test is the most ideal. Can be tested in multiple layers.
Fourth, the choice of misunderstanding:
In order to reduce the purchase cost, some users choose a constant temperature and humidity incubator as the constant temperature and humidity incubator, which is somewhat defective, because the current constant temperature and humidity incubators on the market are all ultrasonic humidified cold mist, especially in the test Wet is a phenomenon that leaks and overflows. The temperature fluctuation is relatively large. There is also a great impact on the test materials.
