The constant temperature and humidity test chamber is also called constant temperature and humidity tester, constant temperature and humidity test chamber, thermostat or constant temperature and humidity chamber. The constant temperature and humidity test chamber is suitable for testing the quality of electronic, plastic products, electrical appliances, instruments, food, vehicles, metals, chemicals, building materials, aerospace, medical and other products. This machine is specially designed to test the heat resistance, cold resistance, dry resistance and moisture resistance of various materials. This machine can choose Chinese or English LCD display touch screen screen, easy to operate, easy to edit program, user-friendly design. It displays complete system operating condition related data, execution and setting program curves. An abnormal situation occurs during operation, and the screen automatically alarms to show the cause of the fault and provide troubleshooting methods.
The refrigerant is adiabatically compressed to a higher pressure by the compressor, and the consumed work increases the temperature of the exhaust gas, and then the refrigerant is heat-exchanged with the surrounding medium through the condenser to transfer heat to the surrounding medium. After the refrigerant is adiabatically expanded by the shut-off valve, the temperature of the refrigerant is lowered. Finally, the refrigerant absorbs heat from the higher temperature object isothermally through the evaporator, so that the temperature of the object to be cooled is lowered. This cycle is repeated to achieve the purpose of cooling. The refrigeration system of this test chamber uses a unit of Freon refrigeration system consisting of a French-made Taikang fully enclosed compressor to keep the refrigeration system in optimal operation.
When the programmable constant temperature and humidity test chamber is purchased, please be sure to refer to the following points according to your own test requirements:
Temperature range: The temperature range of the equipment, you can refer to the highest temperature and the lowest temperature value
Cyclic function: Whether the device has a temperature cycle function, that is: repeatedly cycle the curve cycle between temperatures.
Humidity range: Does the device have a humidity function?
Heat load: Many tested electronic products will be tested for power-on. In the case of power-on, the product being tested will heat up, which will generate a load. So sometimes the equipment bought back, if the standard is -20 degrees, but the final temperature can not fall, this is the reason, so be sure to explain the load situation with the manufacturer.
Equipment handling: Please refer to the size of the equipment and the final arrangement of the equipment.
Power supply: Please refer to whether the power of the equipment matches or meets the power of the final laboratory.
Programmable constant temperature and humidity test chamber equipment features:
High-quality appearance, the body adopts arc shape, the surface is treated with matte stripes, and the flat surface has no reaction handle, which is easy to operate, safe and reliable. The rectangular laminated glass viewing window can be used for observation of the test product during the test. The window has a sweat-proof electric heater device to prevent condensation of water and water, and the high-intensity PL fluorescent lamp keeps the illumination inside the box. The double-door isolation of the door is tight and tight, which can effectively isolate the internal temperature leakage. It has an external water supply system, which is convenient for replenishing the humidification tank and automatically recycling it. The controller has multi-stage program editing and temperature or humidity for fast or slope control. The built-in moving pulley is easy to move and place and has a strong positioning screw fixing position. The pump is used to replenish the humidified water so that the equipment can be used in a waterless installation environment.
