Pharmaceutical workshops have strict requirements for environmental temperature and humidity. The temperature and humidity field inspection instrument plays an indispensable role in it. It can accurately measure the temperature and humidity in different production areas of the workshop. During the drug production process, some raw materials are sensitive to humidity, and fluctuations in temperature and humidity may affect the quality of drugs. The inspection instrument can continuously monitor changes in temperature and humidity and provide data support for production process adjustments. Once it is found that the temperature and humidity exceed the standard range, it can immediately notify the staff to intervene to ensure that drug production is carried out in an environment that meets GMP standards and guarantee the quality and safety of drugs.
