15. Intelligent defrosting, monitoring timing, overlift preventer.
16. High safety, including over-lift alarm, menu lock, over-lift prevention, overload protection, and power failure protection.
Principle
The device realizes temperature control through nickel-chromium alloy electric heating wire heater and centrifugal fan to force air circulation (up-out-down-in). Humidity control is carried out by steam humidification through stainless steel sheathed heater. The refrigeration system adopts French Taikang or German BITZER Compressor, uses environmentally friendly R404A and R23 refrigerants, and realizes rapid cooling through air-cooled single-stage or cascade refrigeration. The control system adopts multi-stage program temperature control, and accurate feedback is carried out through PT100 temperature sensor and imported wet and dry bulb humidity sensor.
Applications
Heat resistance test, cold resistance test, dry resistance test, moisture resistance test
Steps
1. Set the required temperature through a dedicated function key.
2. Perform parameter settings such as deviation correction through the auxiliary menu.
3. Select fixed-value operation, scheduled operation, or program mode.
4. Appointment start stop can be set.
5. Monitor real-time temperature operation via touch screen controller Linear dispersion.
6. After the experiment, the device can be automatically stopped.
