According to the needs of the experiment, the medium involved in the experiment is correctly added to the environmental experiment. For example, in a humid experimental box, there is a certain demand for water, and the resistivity should be reduced. There is an economical and convenient pure water on the market. Its electric constant humidity constant temperature The box resistivity is equivalent to distilled water. Let's take a look at its precautions.

1. To ensure the safety of equipment and tests, please install external protective grounding and power supply according to technical specifications;

2. It is strictly forbidden to use this equipment for the test of flammable, explosive, toxic and strong corrosive materials;

3. Non-professionals are not allowed to disassemble and repair;

4. The equipment should be grounded reliably;

5. During the test, unless necessary, do not open the door or enter the box, otherwise it may cause personal injury and equipment failure;

6. The door lock of the equipment box can only be opened from the outside, and someone must be supervised when entering the equipment box.

7. Put the heating sample, please use an external power supply, please do not directly use the power supply of the device itself;

8. The equipment has a variety of protection measures, please check regularly;

9. When the cabinet temperature is greater than or equal to 55 degrees Celsius, do not turn on the refrigeration compressor to ensure long life and normal operation of the compressor;

10. The inclination angle of products with refrigeration function during transportation should not be greater than 45 degrees Celsius. Restarting after 2 days will help the refrigeration system to work normally and prolong its service life; the main features of the sealing strip of the constant temperature and humidity test chamber are vulcanized EPDM rubber seals Strip: much stronger than PVC strip in terms of sealing elasticity and durability, but due to the need for microwave vulcanization line molding, the processing energy consumption is very high, usually more than 20 times the energy consumption of PVC processing, and the product cannot be reused and is not environmentally friendly , it is not a product advocated by our country.
