Non-Dispersive Infrared Gas Analyzers (NDIR)

NDIR analyzers allow for high sensitivity measurement of a variety of gas components including CO2, CO, CH4, NO, and SO2. Additionally an O2 measurement can be made with a built-in paramagnetic analyzer or external zirconia analyzer.

Infrared Gas Analyzer IR250

The model IR250 is capable of measuring concentration of CO2, CO, CH4, SO2, and NO components in process gas by using the non-dispersive infrared method (NDIR), while measuring O2 with the paramagnetic or zirconia method. It also provides high stability over long periods of time.
A maximum of 4 components including O2 (or up to 3 components without O2measurement) are simultaneously measurable.

Infrared Gas Analyzer IR400

The model IR400 measures the concentration of NO, SO2, CO2, CO and CH4contained in sample gas. Since this instrument incorporates a compact paramagnetic O2 sensor, it allows measureing up to 5 componets simultaneously by using the built-in O2 sensor (up to 4 components if O2sensor is excluded).

Universal Infrared Gas Analyzer IR200

The model IR200 is measures the concentrations CO2, CO, CH4, SO2 and O2contained in sample gas. CO2, CO, CH4 and SO2 are measured by non-dispersion infrared method (NDIR), while O2is measured by paramagnetic method. A maximum of 4 components including O2 (max. of 3 components for other than O2 measurement) are simultaneously measurable.
