Portable Ambient Air Quality Monitoring System
Agasthya 2013 Series
BI 9100
The Agasthya 2013 Series Portable Ambient Air Quality Monitoring Analyzer – BI 9100 is a compact and modular air quality monitoring system designed to deliver accurate real-time and intermittent measurement of ambient air quality parameters across diverse environments.
The BI 9100 AQMS measures key gaseous pollutants including Ozone (O3), Nitrogen Dioxide (NO2), Nitric Oxide (NO), Carbon Monoxide (CO), Carbon Dioxide (CO2), Sulphur Dioxide (SO2), Hydrogen Sulphide (H2S) and other toxic gases using proven Electrochemical and Infrared (IR) sensor technologies.
Designed for portability and flexible deployment, the BI 9100 enables cost-effective air quality monitoring with reliable long-term performance. Measurement data is stored internally and can be accessed remotely in real time via RS-485 communication supporting MODBUS protocol, meeting global requirements for micro-environment air quality assessment.
