In the new version of GSP, higher requirements are put forward for the real-time monitoring of storage temperature and humidity, cold chain logistics and transportation of pharmaceutical enterprises. For cold chain transportation and links, its important part is to realize the whole process of temperature monitoring, to ensure the quality of drugs to a large extent, reduce the loss, so as to meet the needs of consumers as much as possible. This product will track and record the temperature and humidity of the vaccine (environmental goods) to ensure the storage and transportation temperature of vaccine samples. Covering the production, storage and transportation to the distribution end, temperature data can be traced back to the whole process; Storage of continuous recording of temperature status data during transfer and connection; Active alarm for abnormal temperature should avoid reaching the red line value and prevent it in advance.
