8, with a comprehensive protection system, including power overload, leakage, control loop overload short circuit, Compressor, grounding, overtemperature protection, etc., the screen automatically displays and stops when the fault.
9. The heating system uses multi-stage high-temperature and corrosion-resistant alloy heating tubes, coupled with PID modules, to ensure stable temperature and energy saving.
10. The humidification system adopts a circular split humidifier to avoid freezing at low temperature; the humidification tube is made of special alloy, which can be dry burned and protected; the built-in water tank, drawer type water addition, convenient and beautiful; it has a water circulation system that saves 40% water and a water quality filtrate system.
11. The air circulation system uses high-resistance motors, multi-wing fan blades, and specially designed forced air circulation.
12, the refrigeration system adopts imported copper pipeline, which has good flexibility and good shock absorption effect.
13, the controller is imported 7-inch color touch screen, temperature and humidity can be programmed at the same time, high accuracy, with program editing, graphic Linear dispersion display, power-off memory, fault prompt and other functions.
Principle
The device adopts equilibrate Conditioning Control System (BTHC). The induction system transmits the actual temperature and humidity data in the test chamber to the controller, and the controller performs multi-stage intelligent output by controlling the solid state relay (SSR), thereby equilibrating the heating, cooling, humidification, dehumidification and other output power of the temperature and humidity system to ensure that the temperature and humidity in the test chamber are fully stable. The system also has an energy-saving function, which can reduce the power of the instrument to a greater extent and ensure long-term accurate and stable operation.
Applications
Electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products testing mass
Standards
GB5170,2,3,5,6-95 "Environmental test basic parameter method of verification high temperature, constant heat and humidity, alternating humidity cabinet test equipment", GB 2423.2-89 (IEC68-2-2), GB/T 2423.3-93 (IEC68-2-3), GB/T423.4-93 (IEC68-2-30)
Steps
1. Ensure that the instrument is installed in an environment that meets the requirements (there are no items within 60cm around, and the ground is not seriously inclined).
Connect the power supply (220V/50HZ), and note that the allowable voltage fluctuation is +/- 10%.
3, through the imported 7-inch color touch screen controller for human-machine interaction operation.
4. Select or edit the required temperature and humidity test program on the controller (up to 120 sets of programs).
5. Set the temperature and humidity value and running time for each program segment.
6. After confirming the parameters, start the test program.
7. During the test, the sample can be viewed through a large window, or an external test harness can be connected through the left test hole.
8. After the test is completed, the device is stopped according to the program or manually.
9. Check the test data and Linear dispersion displayed by the controller.
Notice
* The operating environment temperature is 0~ 30 ℃, and the working environment temperature is recommended to be 5~ 25 ℃.
Miscellaneous items cannot be placed within 60CM of the instrument to ensure heat dissipation and air circulation.
The installation ground must not be severely tilted.
* Power supply voltage requirements and variation range.
* Make sure there is water in the humidification system tank before use, and regularly check the water quality to filtrate the system.
The equipment has a variety of protection functions. When a fault alarm occurs, please check the fault point and cause displayed on the screen first, and then run it after troubleshooting.
Non-professional personnel should not disassemble or repair the internal components of the equipment.
When placing test samples, please pay attention to the load-bearing capacity of the rack (up to 20KG) and distribute it reasonably to ensure uniform airflow in the box.
* When conducting low temperature tests, the humidification system adopts a split design to avoid freezing, but it is still necessary to pay attention to the operating status.
When the equipment is not in use for a long time, it is recommended to disconnect the power supply and do a good job of cleaning and maintenance.
