Guaranteed ±3℃ at +5℃! We perform frost-free operation by regularly switching the direction of the refrigerant.
The "CRH" is a low-temperature constant temperature and humidity chamber that has achieved long-term continuous stability tests at +5°C for medical and cosmetic products, as well as preservation tests for food. The temperature and humidity difference within the test chamber is referred to as the "maximum and minimum temperature and humidity range," and at +5°C, a guarantee of "±3°C" is provided. During operation at temperatures ranging from +5 to +30°C, a frost-free operation is conducted by regularly switching the direction of the refrigerant to prevent frost buildup on the evaporator. 【Features】 ■ Guarantees +5°C ±3°C ■ Continuous operation at low temperatures ■ Full-range frost-free capability ■ Wide temperature range: -20 to +85°C ■ Long-term preservation tests possible with semi-permeable containers (customizable) *For more details, please refer to the PDF document or feel free to contact us.
