Specifications

This gas analyser is used to measure NO, CO₂, CO, CH₄, SO₂ and O₂. NO, CO₂, CO, CH₄ and SO₂ gases are measured by non-dispersive infrared, while O₂ is measured by the electrochemical, paramagnetic or zirconia method. It can analyse up to 4 gases plus oxygen simultaneously. For the infrared part, it uses a highly sensitive mass flow meter as detector. The single-beam photometric system ensures simplified maintenance and excellent stability over time. The analyser is particularly well suited to monitoring pollutant emissions.

Measurable components		NO, CO2, CO, CH4, SO2 and O2
Measuring principle	Non-dispersive infrared absorption method. Single source, single beam	NO, SO2, CO2, CO, CH4

Repeatability		±0.5% of full scale
Linearity		±1% of full scale
Zero drift		±2% of full scale/week Negligible when using automatic zero calibration
Scale drift		±2% of full scale/week
