Continuous Emission Monitoring System
Agasthya 2013 Series
BI 7000 NDIR – CPCB Compliance

Agasthya 2013 Series BI 7000 NDIR is a CEMS analyzer for continuous measurement of gaseous pollutants in industrial stack and process applications. Using Non-Dispersive Infrared technology, it can be configured for gases including CO, NO, SO2, CO2 and hydrocarbons according to the monitoring duty.

The analyzer combines a touchscreen interface with analog output, RS-485/MODBUS communication, alarms, purge and drain functions, and calibration facilities. Its modular industrial arrangement supports multi-gas measurement where stable continuous emission monitoring is required.

BI 7000 NDIR can support power plants, boilers, cement, refineries, petrochemicals, iron and steel, pulp and paper, pharmaceuticals and waste-incineration applications. It provides a focused CEMS system option for plants seeking continuous stack gas visibility and dependable analyzer performance.
