The temperature control of vaccines during transportation and storage is very important. The vaccine time temperature indicator can intuitively display whether the environment where the vaccine is located exceeds the specified temperature and the duration of the overtemperature, which can ensure the effectiveness and safety of the vaccine and the health of the vaccine recipients. The time temperature indicator has become the standard for global vaccine cold chain compliance. It can ensure the compliance of the temperature of the vaccine during storage and transportation. The LCD vaccine time temperature indicator developed and produced by Freshliance has a large LCD display screen and can set 4 alarm points. If the ambient temperature exceeds the safe range during the monitoring process, the corresponding alarm point 1, 2, 3 or 4 will be displayed on the screen for alarm. The time temperature indicator has an accuracy of ±0.5℃ F.S. and is suitable for temperature cold chain monitoring of pharmaceutical products such as vaccines, reagents, laboratory samples, proteins, and blood products. The temperature control of the transportation and storage environment of vaccines is very important. The Freshliance vaccine time temperature indicator has high accuracy and good stability. It is adapted to the WHO PQS requirements and is used in the global vaccine distribution system, which can help vaccine cold chain managers better protect the effectiveness and safety of vaccines. #timetemperatureindicator #vaccinetemperaturemonitoring #vaccinecoldchain
