Background of using laboratory indoor environment monitoring system
As the core place for scientific research and testing, the stability of the indoor environment in the laboratory is directly related to the reliability of experimental results and personnel safety. With the refined development of experimental technology, the frequent use of various chemical reagents, and the continuous operation of precision instruments, harmful gases such as formaldehyde and VOCs are prone to accumulate inside the laboratory. At the same time, temperature and humidity fluctuations, microbial growth, and other issues may also interfere with experimental accuracy - for example, in a biological laboratory, excessive microbial communities in the air may lead to sample contamination; In the physical and chemical laboratory, abnormal humidity can affect the stability of reagents.
The traditional environmental management method that relies on manual timed recording and local sampling not only has limitations such as data lag and incomplete coverage, but also finds it difficult to cope with sudden environmental changes (such as gas concentration surges caused by ventilation system failures). In addition, regulations such as the "General Requirements for Laboratory Biosafety" continuously refine the control standards for experimental environments, making the demand for real-time monitoring and dynamic warning increasingly urgent. In this context, laboratory indoor environmental monitoring systems have emerged, providing data support for precise control and risk prediction of experimental environments through continuous perception and intelligent analysis of multidimensional environmental parameters. This not only ensures the scientific nature of scientific research work, but also builds a protective barrier for personnel health.
