Buy the constant temperature and humidity box price precautions, carefully purchase!
One: four major issues in the price of constant temperature and humidity box purchase
1. The size selection of the constant temperature and humidity test chamber is generally determined according to the size of the test product.
2, constant temperature and humidity test box power supply selection whether it is 220V or 380V are three-phase power interface, if the temperature is below -40 degrees, and the box is above 225L, it is recommended to choose 380V four-phase power interface, because of this The electricity used throughout the laboratory is relatively stable and beneficial to the life of the equipment itself;
3, air cooling and water cooling options: constant temperature and humidity box is generally sufficient to use air cooling, the use of water cooling is generally a large constant temperature and humidity chamber or large box of rapid temperature rise and fall test machine, the general thermal shock test box is water cooled More; four, constant temperature and humidity box use environmental environment test,
4. The reliability test of the constant temperature and humidity chamber has a long test period. The test object is sometimes a military product with high value. During the test, the test personnel often have to operate or test around the site. Therefore, the environmental test equipment must be required. It has the characteristics of safe operation, convenient operation, reliable use and long working life to ensure the normal operation of the test itself. The various protection, warning measures and safety interlocking devices of the test equipment should be perfect and reliable to ensure the safety and reliability of the test personnel, the tested products and the test equipment itself.
Two: How to maintain the price of constant temperature and humidity box?
1. To avoid machine failure in the constant temperature and humidity test chamber, please provide power supply within the rated voltage range.
2. In order to prevent electric shock or malfunction and malfunction, do not turn on the power before installation and wiring are completed.
3. Please wipe the meter with a dry cloth. Do not use alcohol, gasoline or other organic solvents. Do not splash water on the meter. If the meter is immersed in water, stop using it immediately, otherwise there is danger of electric leakage, electric shock or fire.
4. It is forbidden to disassemble, process, modify or repair the constant temperature and humidity machine without authorization, otherwise there will be danger of abnormal operation, electric shock or fire.
5. Constant temperature and humidity box The ventilation hole of the body should be kept open to avoid malfunction, abnormal operation, reduced life and fire.
Three: What are the precautions for the price of constant temperature and humidity boxes?
1. Do not use the machine if it is found to be damaged or deformed when unpacking.
2. This product is a non-explosion-proof product. Please do not use a constant temperature and humidity machine in the environment with flammable or explosive gas.
3. In the constant temperature and humidity test chamber of Shanghai, please try not to open the constant temperature and humidity test chamber door. If it is opened at high temperature, it may cause burns to the operator. Opening at low temperature may cause frostbite to the staff and may cause the evaporator to freeze. , affecting the cooling effect. If you must open it, please do some protection work.
4. Regularly check the terminal screws and the holder, please do not use it under loose conditions. Before the instrument is in operation, the safety should be fully considered before the operation of modifying settings, signal output, starting, stopping, etc., and the wrong operation may cause damage or malfunction of the working equipment.
