1. The product has beautiful appearance, reasonable structure, precise process, simple and convenient operation, stable and reliable performance.
The controller uses a large color liquid crystal man-machine touch dialog LCD interface, with Chinese and English display, simple operation, and can realize remote control of RS232 computer interface.
3. The original imported Japanese "Sanyo" brand fully enclosed Compressor (optional from France Taikang Compressor) and imported parts from many countries are used, and the refrigerant adopts American environmentally friendly refrigerant.
4, with automatic, high precision system loop, using P.I.D automatic calculation control, temperature control with High Accuracy and High Stability.
5. Specially designed air circulation circulation and sensing system ensure uniform temperature in the box and avoid dead ends.
6, the use of enlarged observation window, equipped with 4 layers of tempered Glass, a wide field of vision.
7, with a comprehensive protection system, including power overload, leakage, control loop overload, short circuit, Compressor, grounding, over-temperature protection and alarm prompts.
8. Adopt multi-stage heating tubes with PID modules to ensure stable temperature and energy saving; heating tubes are made of high-temperature and corrosion-resistant alloy tubes.
9, using a circular split humidifier to avoid low temperature freezing; humidification tube made of special alloy, can be dry burning protection, with high temperature alarm module; with water circulation system water saving 40%, and water quality filtrate system.
10. Adopt high-resistance air circulation motor, multi-wing fan blades and specially designed forced air circulation system.
11. The refrigeration system adopts imported copper pipeline, which has good flexibility and good shock absorption effect.
12, 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, fault prompt, power-off memory recovery and other functions.
Principle
This equipment adopts equilibrate Conditioning Control System (BTHC). The induction system transmits the actual temperature and humidity data in the test chamber to the controller. The controller controls the SSR (solid state relay) to equilibrate the output power of the temperature and humidity system in a multi-stage intelligent output mode, thus ensuring the full stability of the temperature and humidity in the test chamber. The system also has an energy-saving function, which can reduce the power of the instrument to a greater extent and ensure the long-term accurate and stable operation of the instrument.
Applications
Electronic, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, aerospace and other products for mass testing
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. Perform human-machine interaction through a large color LCD touch screen.
2. Set the required temperature and humidity program Linear dispersion on the controller, which can be edited, cleared, and inserted into the program segment.
3. Set the number of program executions and the running time of each period.
4. Start the device, the system will automatically run according to the set program, and display the execution status and Linear dispersion in real time.
5. During operation, the sample status can be observed through the observation window.
6. When the operation is completed or an abnormality occurs, the device will prompt and perform protective actions according to the settings.
Notice
• Miscellaneous items should not be placed within 60CM of the instrument.
• The installation ground should not be severely tilted.
• The recommended working environment temperature is within the range of 0~ 30 ° C (or 5~ 25 ° C).
The operating voltage is 220V/50HZ, and the allowable voltage variation is +/- 10%.
• The equipment has a variety of protection functions. When an abnormality occurs, the screen will display the fault point and cause and automatically shut down. Please check in time.
• When adding water, please use the drawer type water filling box provided by the equipment, and pay attention to the maintenance of the water quality filtrating system.
• When conducting low temperature tests, the circular split humidifier can effectively avoid the problem of freezing in the sink.
