  1.Use in food storage and transportation

  As the food storage and transportation process time is not a short-term problem, but the relative equilibrium humidity in food preservation is an important indicator to ensure food safety, the relative equilibrium humidity directly affects the growth of colonies. For example:In the equilibrium relative humidity of 95% RH to 91% RH range, easy to breed colonies of salmonella, borrelia, lactic acid bacteria, mold and yeast. Food preservation period is also related to the temperature and equilibrium relative humidity, the equilibrium relative humidity value of 81% RH cake, its shelf life is 14 days at 27C, 24 days at 21C, if the equilibrium relative humidity is increased to 85% RH, these indicators will be reduced to 8 days at 27C, 12 days at 21C. The equilibrium relative humidity of hygroscopic substances plays a decisive role. The equilibrium relative humidity is defined as the value of humidity obtained by the surrounding air if the substance does not exchange water with the air. This definition makes it clear that in order to successfully store and maintain these products, the control of the environmental climate and the packaging must be carefully specified. At the same time, many foods are preserved in too dry conditions and their taste is somewhat spoiled. For this situation, real-time recording of temperature and humidity changes is required to ensure that food safety enters the consumer's mouth... When transporting frozen and refrigerated foods over long distances or by sea, it is important to prove that the goods have been kept at the specified temperature and humidity at the time of receipt. The solution to the dispute is to put a temperature and humidity data logger in the cargo hold at the time of shipment and activate it, which will faithfully record the temperature and humidity changes throughout the transportation process, and the carrier's liability will be immediately known. At present, KFC and other well-known fast food companies are using temperature humidity data loggers.

  

  2. Use in the vaccine cold chain

  In the cold chain storage and transportation process of vaccines, vaccines and other biological products shipped from the finished product warehouse of pharmaceutical plants to the vaccination of the people concerned, the monitoring and recording of the temperature of the environment they are in can confirm their quality and ensure the effect of immunization. The temperature and humidity data logger conveniently and reliably solves this problem.

  3.Application in building materials experiment

  During the drying process of building materials, especially concrete, we should pay attention to its drying trend, which is one of the indicators for evaluating products and provides reliable data for building constructors. The application of temperature and humidity data logger can record and provide this data to the building materials research party, which will provide useful help for the construction. Especially in military construction, time is life, accurate grasp of concrete drying time for the first to the enemy, for the effective provision of living forces to the battlefield to provide a guarantee, this function can all be completed by the temperature and humidity data logger.
