1. Frost-free type: It completely avoids the inconvenience caused to users by the temperature and humidity drift caused by the non-defrosting function of domestic products and the large fluctuations in temperature and humidity caused by imported products during the defrosting process.
2. Refrigeration technology with hot gas bypass, the speed of the circulating fan is adjustable in three stages, which is in line with the characteristics of European and American products. It can run continuously for a long time, and the temperature and humidity do not drift.
3. Equipped with (150mm × 50mm) large LCD screen, intelligent programmable controller using microcomputer fuzzy PID control technology, with 30 different program settings, 99 cycles can be cycled, appointment time and temperature and humidity can be set, with Visual alarm prompt sign and sound alarm function.
Adopt Swiss imported capacitive humidity sensor, German original ABB Pt100 platinum resistance temperature sensor, German imported EBM condensing fan, imported brand compressor.
4. The handle of the outer box door adopts the German-American style 90°C rotating four-point locking, which has the function of forced closing. There is no vibration in the box during the closing of the box door, and the tiny test objects in the box will not be knocked down. There is a 5mm tempered glass door with positioning function inside, and there is a waterproof lighting on the outside of the top of the inner tank. When the outer box door is opened, the conditions inside the box can be observed in all directions through the inner tempered glass door, and the temperature and humidity in the box will not fluctuate greatly. The internal configuration of 304﹟ stainless steel partition is convenient for users to adjust the position freely. There is a 40mm test hole with a soft silicone plug on one side of the case to facilitate user monitoring.
5. The new diffused air duct circulation system ensures uniform distribution of temperature and humidity. The water system adopts the advanced design method of automatic water replenishment and recycling. Equipped with leakage protection, over-temperature protection alarm, low water level alarm, scheduled start and stop, clock memory, live indication, power failure memory, and call recovery functions. Sheet metal processing adopts the combination of CNC machine tools imported from Germany and laser processing technology and moulding. The outer box adopts high-quality cold-rolled steel plate, the inner tank adopts 304﹟ stainless steel plate, the outer box adopts powder spray technology, and the bottom of the box adopts an integrated welding structure of rectangular square steel to ensure that the overall strength of the box body meets the international standards of similar products. The box body adopts three-layer super-thick insulation layer technology, and high-density polyurethane insulation material is selected, which meets the international standards of similar products.
11. Refrigeration system: equipped with compressor overheating, compressor overcurrent, compressor overpressure, and condensing fan overheating protection devices.
Test box: equipped with adjustable over-temperature, test space temperature fuse, air-conditioning pass limit over-temperature, fan motor overheat protection device.
Others: Equipped with total power phase sequence and phase loss protection, leakage protection, overload and short circuit protection devices.
