Constant temperature and humidity laboratory
2015-11-12
The constant temperature and humidity laboratory is to make the temperature and humidity of a laboratory meet the requirements of a standard atmosphere for humidity regulation and testing through some special equipment and technical methods. The constant temperature and humidity laboratory is the infrastructure for product quality inspection and control of production enterprises and commodity quality inspection and control in the circulation field. The constant temperature and humidity laboratory is widely used in cotton textile, wool textile, chemical fiber, paper, packaging, tobacco production enterprises, quality inspection, fiber inspection and other departments. According to relevant ISO and GB standards, the inspection of physical items of commodity quality such as textiles, textile raw materials, paper, paper products and cartons must be carried out under standard atmospheric conditions. In addition to the constant temperature and humidity laboratory with conventional temperature and humidity, there are other special constant temperature and humidity laboratories with special requirements such as 5-18 ℃ low temperature, 30-80 ℃ high temperature, relative humidity less than 40% RH low humidity, and relative humidity higher than 80% RH height.
