Application Background of the Indoor Air Monitor for Biochemical Laboratories
As the core sites for conducting experiments such as microbial culture, gene sequencing, and biopharmaceutical R&D, biochemical laboratories have an indoor air environment that directly affects the life safety of laboratory personnel and the accuracy of experimental results. During the experimental process, frequently used chemical reagents (e.g., formaldehyde, ethanol, and strong acid/alkali solutions) are prone to volatilization, producing toxic and harmful gases. Microbial samples may form aerosols and spread due to improper operation, and there is also a risk of leakage for biological agents used in gene editing experiments. If these pollutants accumulate indoors, they may not only cause acute health issues for laboratory personnel, such as dizziness and respiratory tract irritation, but also lead to chronic poisoning, allergic reactions, and even bio-safety accidents with long-term exposure.
However, the traditional air management methods in biochemical laboratories have obvious shortcomings. On one hand, they rely on manual sampling with portable detectors at regular intervals, resulting in low detection frequency (usually 1-2 times a day). This makes it difficult to capture the moment of sudden pollutant leakage (e.g., spilled reagent bottles, fume hood malfunctions) in real time. By the time excessive levels are detected, the pollutants may have spread throughout the entire laboratory, missing the optimal disposal opportunity. On the other hand, manual detection mostly targets single pollutants (e.g., formaldehyde, ammonia gas) and cannot simultaneously monitor multi-dimensional indicators such as temperature, humidity, particulate matter concentration, and bioaerosols. Nevertheless, biochemical experiments have strict requirements for the environment—for instance, microbial culture requires constant temperature and humidity, while gene experiments demand a low-dust environment. Monitoring only single indicators makes it difficult to ensure the stability of the experimental environment, which may lead to problems such as deviations in experimental data and sample contamination.
Introduction to the Indoor Air Monitoring System
The OSEN-SN10 Indoor Air Quality Monitor and OSEN-SN20 Indoor Air Quality Monitor are specialized terminal devices designed for indoor environment monitoring. Equipped with high-precision and high-reliability sensors, they can sensitively detect a variety of potential indoor pollution sources (such as formaldehyde, TVOC, PM2.5, carbon monoxide, ammonia gas, hydrogen sulfide, etc.). These monitors feature strong resistance to cross-interference, high accuracy, and quick response.
Basic Parameters
The OSEN Indoor Air Quality Monitoring System integrates real-time monitoring of PM2.5, PM10, temperature, humidity, O?, CO, CO?, formaldehyde, VOCs, noise, and other indicators. It can measure the indoor ambient air quality with relatively high accuracy, establish an atmospheric environment data monitoring and analysis system, and is equipped with functions such as a high-concentration audio-visual alarm and linked control system.
Indoor Environment Monitoring Cloud Platform
To facilitate customers in viewing the data monitored by indoor environment monitoring devices, OSEN has newly launched a web-based online management cloud platform, along with multiple display methods including mobile terminals (APPs, mini-programs, official WeChat accounts) and on-site window software. After logging in with their accounts, users can check the real-time online status of indoor environment monitors, real-time data, historical data, and data curve analysis charts online. The platform also features functions such as device management, user management, and data report generation.
