The high and low temperature chamber is also known as environmental test chamber is a common testing equipment that simulates extreme weather environments more realistically through the cyclic changes of high temperature, low temperature, and humidity, and obtains accurate test results.
1. SUS304 mirror stainless steel studio, flat reaction handle.
2. Vacuum tempered glass observation window, defrosting function, built-in independent steam humidification for observation of experimental conditions at any time, and uniform humidity.
3. Turbine centrifugal forced air supply, the temperature is more uniform.
4. Original imported compressor, environmentally friendly R404 refrigerant, spray defrost function, to ensure stable and efficient refrigeration.
5. Universal pulley at the bottom, easy to move.
