Constant temperature and humidity laboratory is a laboratory by some special equipment and technical methods and makes the indoor temperature and humidity meet one time wet and experiment with the requirements of the standard atmosphere. Constant temperature and humidity laboratory is production enterprise and the product quality inspection and control of the circulation in the field of quality inspection control infrastructure. Constant temperature and humidity laboratory are widely used in cotton spinning, wool spinning, chemical fiber, paper, packaging, tobacco production enterprises and quality inspection, QianJian departments, in accordance with the relevant ISO and GB standards, textiles, textile materials, paper, paper and carton of goods such as quality inspection of physics project required in standard atmospheric conditions. Textiles and textile raw material inspection standard atmosphere according to the provisions of the ISO139 and GB6529 standard temperature 20 + 2 ℃, relative humidity of 65% plus or minus 2%; Paper, paper and carton goods inspection standard according to the regulations of the ISO187 and GB10739 standard atmosphere, the temperature of 23 + / - 1 ℃, relative humidity of 50% plus or minus 2%. In addition to the normal temperature and humidity in the constant temperature and humidity laboratory, there are other special 5-18 ℃ low temperature, 30-80 ℃ high temperature, relative humidity is less than 40% RH low humidity, relative humidity above 80% RH special requirements such as the humidity of the constant temperature and humidity of lab.
