14. Intelligent defrosting, monitoring timing, overlift preventer.
15. High safety, with multiple protections such as over-lift alarm, menu lock, over-lift prevention, overload protection, and power-off protection.
Principle
The equipment is heated by a nickel-chromium alloy electric heating wire heater, humidified by a stainless steel sheathed heater, and cooled by a cascade refrigeration system driven by a French Taikang or a German BITZER Compressor. A centrifugal fan is used to achieve broadband forced air circulation (up and down) to ensure uniform temperature and humidity in the box. The controller collects data through a PT100 temperature sensor and an imported wet and dry bulb humidity Sensor to perform multi-stage program temperature control to achieve accurate temperature and humidity control.
Applications
Electronic and electrical, automobile and motorcycle, aerospace, ship weapons, colleges and universities, R & D institutions and other related products of parts and materials in high temperature, low temperature, heat and humidity environment performance testing
Steps
Connect the power supply (AC220V +/- 10% or AC380V/415V +/- 10%).
2. Set the required temperature and humidity program or select the fixed value/timing operation mode through the touch screen controller.
3. Put the sample on the inner shelf and close the box door.
4. Start the equipment and start the experiment.
5. The experimental situation can be observed in real time through the observation window.
6. After the experiment is completed, the device can automatically stop and take out the sample according to the setting.
Notice
* Equipment should be placed in a well-ventilated, no direct sunlight, no strong electromagnetic interference environment.
Please ensure that the water supply system (pump) is working properly before use to avoid dry burning.
* Do not switch the Compressor on and off frequently to avoid affecting the service life.
* When the equipment is running, do not open the door frequently, so as not to affect the temperature and humidity Stability and experimental accuracy.
Check and clean the condenser regularly to ensure good heat dissipation.
Non-professional personnel should not disassemble or modify the safety protection devices of the equipment (such as fuse switches, fuses, over-temperature protectors, etc.).
When the equipment malfunctions and alarms, it should be stopped for inspection before use.
When moving the device, use the built-in pulley to move smoothly to avoid severe vibration.
When not in use for a long time, the power supply should be cut off and a good cleaning and maintenance work should be done.
