How to choose the constant temperature and humidity box
The constant temperature and humidity box can also be called a constant temperature and humidity test machine, a constant temperature and humidity test box, a constant temperature machine or a constant temperature and humidity box. It is a device used to detect the performance of materials in various environments and test various materials for heat resistance, Cold resistance, dry resistance, moisture resistance. It is suitable for testing the quality of electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other products. The following is a brief explanation by the constant temperature and humidity box manufacturer Shanghai Linpin, if you choose the right constant temperature and humidity box.
The first step: the choice of size, the general constant temperature and humidity box is determined according to the size of the test product.
Step 2: Choose the power supply of the constant temperature and humidity box, whether it is 220V or 380V, it is a three-phase power supply interface. If the temperature is below -40 degrees, and the cabinet is above 225L, it is recommended to choose a 380V four-phase power interface Because this is more stable for the entire laboratory, it is also good for the life of the equipment itself.
The third step: the choice of air cooling and water cooling. The constant temperature and humidity box is usually air cooling. The water cooling is usually a large temperature constant temperature and humidity test chamber. The machine uses more water cooling.
The fourth step: the selection of the environmental test of the incubator, especially in the reliability test, the test period is long, and the test object is sometimes a high-value military product. During the test process, the tester must often operate around the site Or test work, it is required that the environmental test equipment must have 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, alarm measures and safety interlocks of the test equipment should be perfect and reliable to ensure the safety and reliability of the tested products and test equipment of the test personnel.
