The BW-BAD811 bioaerosol automatic monitoring device can perform real-time online monitoring of the concentration of biological particles in the surrounding environment. When the detected concentration of biological particles exceeds the limit, it automatically completes subsequent sampling and detection, and emits sound and light alarms for positive detection results. Adopting unmanned automation integration design, it can independently achieve integrated steps of environmental aerosol monitoring, sampling, and monitoring. Operators can monitor the real-time operation status of the equipment remotely through display devices. Real time monitoring and protection of bioaerosols suitable for key fixed target environments....
