Overview
JIANGKAI NBC-HW-50 (-40 ℃) Constant Temperature and Humidity Chamber is a test equipment used to simulate high temperature, low temperature and constant heat and humidity, alternating heat and humidity environment. The equipment has an Interior volume of 50L, Temperature range -40 ℃ to 150 ℃, and humidity control range of 20% RH to 98% RH. It is mainly used for environmental adaptability testing of parts and materials of electronic, electrical, household appliances, automobiles and other products.
Features
1. Adopt full-tight Compressor imported from France, with environmentally friendly refrigerant R404A, the refrigeration system is efficient and reliable.
2. Equipped with the original Korean imported TEMI880 full Chinese 7-inch LCD touch screen controller, the operation interface is intuitive, and supports both temperature and humidity program control and Linear dispersion display.
3. The control system has high accuracy, temperature control accuracy up to +/- 0.1 ℃, humidity control accuracy up to +/- 1% RH, and has multiple sets of PID control and automatic calculation functions.
4. The program capacity is large, with a maximum support of 100 sets of programs, with a total memory capacity of 5000 segments (SEGMENTS), meeting the needs of complex testing.
5. Equipped with power-off program memory and automatic connection execution function after power-up to ensure test continuity.
6. The box door is equipped with three-layer vacuum observation window, which has good thermal insulation performance and is easy to observe.
7. Key electrical accessories such as pressure controllers, solenoid valves, contactors, etc. are made of internationally renowned brands to ensure the stable operation of the equipment.
Principle
The Constant Temperature and Humidity Chamber uses a refrigeration system (Compressor, condenser, evaporator, expansion valve, etc.) and a heating and humidification system (heating rod, humidification tube, etc.) to work together to create and maintain a set temperature and humidity environment in a closed test chamber. The control system monitors the environment in real time through temperature sensors (Pt100) and humidity sensors, and uses PID algorithms to precisely adjust the output of refrigeration, heating, humidification and other actuators to quickly reach and stabilize the temperature and humidity at the set value to simulate the test environment required by the product.
Applications
Electronic, electrical, household appliances, automobiles and other product parts and materials
Standards
GB5170.2, GB5170.3, GB5170.5, GB5170.6-95 "basic parameters of electrical and electronic products environmental test equipment method of verification low temperature, high temperature, constant heat and humidity, alternating humidity cabinet test equipment", GB 2423.1-89 (IEC68-2-1), GB 2423.2-89 (IEC68-2-2), GB/T 2423.3-93 (IEC68-2-3), GB/T 2423.4-93 (IEC68-2-30)
Steps
1. Turn on the power supply and turn on the main switch of the device.
2. Enter the operation interface through the 7-inch touch screen controller.
3. Edit or select the existing test program as needed, and set the target temperature, humidity, and time for each stage.
4. Put the sample to be tested into the test chamber and close the box door.
5. Start the test program on the controller and the device starts running.
6. During the test, the temperature and humidity Linear dispersion, program number, remaining time and other information can be observed in real time through the screen.
7. After the test is completed, the device automatically stops or completes the program to remove the sample.
8. If follow-up testing is required, repeability steps 3-7; if no longer in use, turn off the power of the device.
Notice
* The equipment should be installed in a well-ventilated, non-direct sunlight, away from heat sources and flat ground.
Do not use this equipment near flammable, explosive or corrosive substances.
When placing the sample, ensure that the air circulation in the box is not affected, and the total load should not exceed the specified limit.
When the equipment is running, do not open the door frequently to avoid affecting the stability of temperature and humidity and the lifespan of the equipment.
Regularly check the refrigerant, Filter and other components to ensure that the equipment is in good working condition.
After conducting a high-temperature or high-humidity test, if you need to open the box door, please pay attention to the high-temperature and high-humidity gas ejection to avoid burns.
When the equipment malfunctions, please check the fault information displayed by the controller first, and troubleshoot according to the prompts, or contact a professional to deal with it.
Before maintenance, be sure to cut off the total power supply of the equipment.
