Portable Multi-Gas Analyzer NDIR-GFC

MIR 9000P

The MIR 9000P belongs to the new generation of ENVEA gas monitors, showcasing eco-design, IoT and on board intelligence.

It measures simultaneously 8 gases – NOx, SO2, CO, CO2, CH4, N2O, O2 and residual H2O – and uses the non-dispersive infrared method (NDIR-GFC) with gas filter correlation. O2 is measured by a built-in SRM paramagnetic sensor.

The analyzer has been designed to meet the specific needs of on-site regulatory measurement providing superior mobility, robustness, accuracy and compliance. All this makes up for a unique gas emission monitor offering high productivity and low operational cost.
