The necessity of temperature and humidity (relative humidity) standards

With the rapid development and popularization of science and technology, there are more and more high-performance equipment, and all walks of life have higher and higher requirements on temperature and humidity. Such as:



Food industry: temperature and humidity are crucial for food storage. Changes in temperature and humidity will lead to food deterioration and food safety problems.



Archive management: paper products are extremely sensitive to temperature and humidity. Improper preservation will seriously reduce the storage life of archives.



Greenhouse: the growth of plants for temperature and humidity requirements are very strict, improper temperature and humidity, plants will stop growing, or even death.



Animal breeding: different animals will show different growth conditions at different temperatures. The goal of high quality and high yield depends on the appropriate environment.



Drug storage: according to relevant national requirements, drug storage must be controlled according to the corresponding temperature and humidity.



The above is only a part of the more common industry applications, more limited to the length of the industry, not enumerated.



Necessity of temperature and humidity standards:



With the extensive use of temperature and humidity sensors and temperature and humidity meters, it is inevitable to have systematic metrological verification to ensure the unified standard and accuracy traceability of the physical quantity detection. It is necessary to equip national extremely standard laboratory, provincial and municipal metrological research institute, research institutes of various industries, quality inspection institutions, university laboratories, enterprise research and development centers and laboratories, etc., with reliable temperature and humidity metrological verification devices.



The measuring and verifying device of temperature and humidity can be divided into two parts. The second is the humidity standard.



Humidity verification is affected by temperature, and temperature should be considered in all cases.
