Overview
Programmable constant temperature and humidity testing machine is mainly used to detect the performance of materials in various environments, test the heat resistance, cold resistance, dry resistance and moisture resistance performance of various materials. Suitable for mass detection of electronics, electrical appliances, communications, meters, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products. Using equilibrate Conditioning Control System (BTHC), the induction system transmits the actual data in the test chamber to the controller. The controller controls the SSR multi-stage intelligent output, equilibrate the output power of the temperature and humidity system to ensure that the temperature and humidity in the test chamber are fully stable, and has the function of energy saving, reducing the power of the instrument and ensuring long-term accurate and stable operation.
Features
1. The product has beautiful appearance, reasonable structure, precise process, simple and convenient operation, stable and reliable performance.
The controller uses a large-scale color liquid crystal man-machine touch dialog LCD interface, which is easy to operate, easy to learn, stable and reliable. It displays the operating status of the system in both Chinese and English, and can realize RS232 computer interface docking. It supports computer remote control.
3. The refrigeration circulation system adopts the original imported Japanese "Sanyo" brand fully enclosed Compressor (optional French Taikang Compressor), the components are imported from Japan, France, the United States, Italy, etc., and the refrigerant adopts the American environmentally friendly refrigerant (R23A, R404A).
4. A 50mm diameter test hole is reserved on the left side of the test chamber.
5, with automatic, high-precision system loop, using P.L.C lock processing and P.I.D automatic calculation control, the whole area of High Accuracy Temperature, High Stability.
6, special design air circulation circulation system and sensing system, the trend and return air sensor detection and control, to ensure Temperature Uniformity, avoid dead angle.
7. Adopt enlarged observation window, 4 layers of whole empty tempered Glass, wide field of vision.
8. The instrument has a comprehensive protection system, including power overload protection, leakage protection, control loop overload, short circuit protection, Compressor protection, grounding protection, over-temperature protection, alarm and sound prompts, etc., and automatically displays the fault point and cause and stops when abnormal.
Principle
The equilibrate Conditioning Control System (BTHC) is adopted, and the induction system transmits the actual data in the test chamber to the controller. The controller controls the SSR multi-stage intelligent output and the output power of the equilibrate temperature and humidity system to ensure that the temperature and humidity in the test chamber are fully stable, and It has the function of energy saving, reducing the power of the instrument, and ensuring long-term accurate and stable operation.
Applications
Electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace
Steps
Connect the power supply to ensure that the voltage meets the requirements (380V/50HZ, the allowable value of variation is +/- 10%).
2. Set the test parameters through the controller, including temperature, humidity, etc.
3. Start the instrument and monitor the operating status.
4. After the test is completed, turn off the instrument and disconnect the power supply.
Notice
• The use environment temperature should be maintained at 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Miscellaneous items cannot be placed within 60CM of the instrument.
• Power supply voltage variation allowable value is +/- 10%.
• When there is an abnormal situation, the instrument will automatically display the fault point and stop, which needs to be dealt with in time.
