Temperature and humidity recorders have emerged with the improvement of industry standards and the increasing demand for temperature and humidity monitoring. Temperature and humidity measurement is a newly developed field in modern measurement, especially humidity measurement is constantly advancing. After the evolution of electrical measurement from length method, dry wet method to today, temperature and humidity measurement technology has become increasingly mature. Traditional temperature and humidity measurement techniques cannot meet the requirements for real-time monitoring of the entire product process, and based on these changes, the safety of the storage and transportation process is determined, leading to the emergence of new temperature and humidity measurement instruments, such as temperature and humidity recorders.
The emergence of temperature and humidity recorders has shown more versatility. A temperature and humidity recorder is an instrument that measures temperature and humidity parameters and stores them in internal memory at predetermined time intervals. After completing the recording function, it connects to a PC and uses adaptive software to extract and analyze the stored data according to its values and time. This instrument can be used to determine that there have been no incidents that endanger product safety during the storage and transportation process, experimental process, and other related processes. For example, in the transportation process of vaccines, vaccines and other biological products, when vaccines, vaccines and other biological products are shipped from the finished product warehouse of pharmaceutical factories to the cold chain storage and transportation process for vaccination of relevant populations, their quality can be confirmed by monitoring and recording the temperature of the environment they are in, ensuring the effectiveness of immunization. The temperature suitability recorder conveniently and reliably solves this problem.
Monitoring and managing the cold chain system is an important part of ensuring the quality of vaccines and vaccines, and doing a good job in planned immunization work. Previously, due to technological and financial limitations, there was a lack of equipment for convenient and effective monitoring of the cold chain in complex environments such as vaccine transportation and storage. Therefore, there is a lack of supervision and discrimination basis for violations such as storing and transporting bacteria and vaccines at room temperature, and using expired bacteria and vaccines for vaccination. The current temperature and humidity recorder has greatly improved the occurrence of this situation and has shown a more important position in the current cold chain system.
