The new intelligent environmental experiment box adopts a new color touch screen display and PLC computer system control, which can realize high-precision constant temperature and humidity artificial climate simulation experiment environment. It is the necessary experimental equipment for the production and testing of bioengineering, medicine, forestry, environmental science and decorative materials.

The constant temperature box is made of mirror stainless steel, the surface is smooth and non-condensing, and it does not absorb formaldehyde, which ensures the detection accuracy; the insulation adopts advanced thermal insulation materials, and the box door adopts a special material with formaldehyde-free sealing strip, which has good thermal insulation performance and sealing performance.

The environmental test box is composed of air pump, flow meter, water bath spray, cooling coil, heating pipe, water level switch, compressor, condenser, fan, lighting, temperature control device, plc central control system, large LCD touch screen, etc.

The environmental test box developed and produced by our company adopts the internationally popular dew point temperature humidity control method to control the humidity in the box, and the temperature control adopts step-free dew point heat exchange to ensure the stability of humidity and temperature. Before the experiment, check and adjust the temperature value required for the setting, and the saturation dew point temperature (the temperature of the water bath spray tower) corresponding to the relative humidity to be obtained. After the machine is turned on, the experiment and recording are automatically completed. The air pump will turn the natural air into a saturated gas with a dew point of the set temperature, and input it into the incubator at a rate of 1 cubic meter per hour. (Note: About 1-3 hours after the dew point temperature reaches the set value, the humidity in the incubator is close to equilibrium.)

The company pioneered the internal circulation running state and the external circulation running state, and perfected the test process of various environments and various experimental states. The external circulation state is prepared for the experiment to ensure the purity of the air in the box, and the internal circulation state is activated during the experiment to ensure the test. data accuracy. It is easy to switch between inner and outer loops. (It can also be customized to implement time conversion).

The company innovatively set up an independent humidity balance system, and realized the separation of water and gas in the process of dehumidification and humidification, so as to make the experimental data more accurate. A set of test reagent injection device (empty injection) is installed on the right side of the main box, which is convenient and practical, and can complete the requirements of injecting various reagents without opening the door.

The environmental experiment box is equipped with a particulate filter, and all TVOC filter interfaces are reserved. It can be upgraded and installed according to customer needs. Meet a variety of experimental environments. (Note: The particulate filter should be checked for dust and dirt blockage for about 20-30 days and cleaned or replaced in time.)
