ZR-7500 Portable Bioaerosol Monitor
Overview
The ZR-7500 portable bioaerosol monitor uses Mie scattering and ultraviolet-induced fluorescence (UV-LIF) methods to detect bioaerosol particle size, enabling real-time monitoring of the concentration of airborne biological agents (bacteria, spores, viruses, toxins, etc.).
It is widely used for monitoring airborne biological agents in indoor environments, such as hospital cleanrooms, biopharmaceutical cleanrooms, public spaces, manually controlled indoor environments, public transportation environments, and indoor aquaculture environments.

Long time incubation VS. Real-time monitoring
Current air microbial monitoring relies on the traditional "sample collection- culture-analysis" method. This process takes one to seven days to produce test results, requiring significant human, material, and time resources.
Against increasingly stringent regulatory requirements, rising labor costs, and the increasing demand for intelligent automation, traditional monitoring methods are increasingly unable to meet demand, necessitating the urgent need for advanced alternative technologies.
