The constant temperature and humidity box is a main product in environmental testing equipment, and it is also a equipment with a large demand from various enterprises. Its main function is to test whether the products produced by various enterprise units are qualified. As a testing device, what standards need to be met during the production process of the constant temperature and humidity chamber are particularly important. Most domestic test equipment is produced in accordance with the national standard (GB / T2423). The standards met by the constant temperature and humidity chamber are: GB / T 2423.1-2008 Test A "Low Temperature Test Method"; GB / T 2423.2-2008 Test B "High Temperature Test Method"; GB / T 2423.3-2006 Test C "Constant Humidity and Heat Method "; GB / T 10586-2006" Technical Conditions for Humidity and Heat Test Chamber "and other national standards are designed and manufactured, and various high and low temperature and humidity environment tests can be conducted. As one of the well-known enterprises in the field of environmental testing equipment in China, Beijing Yashilin strictly meets the standards in accordance with international requirements. The technical parameters of the constant temperature and humidity box are as follows: temperature range: 0 ° C to 150 ° C temperature uniformity: ± 2 ° C (at no load) Temperature fluctuation: ± 0.5 ° C (at no load) Humidity range: 30% to 98% RH ( When the temperature is 25 ℃ ～ 80 ℃) Humidity deviation: +2, -3% RH Heating rate: 1.0 ℃ ～ 3.0 ℃ / min Cooling rate: 0.7 ℃ ～ 1.0 ℃ / min Time setting range: 1 ～ 9999 hours : AC380V three-phase four-wire system
