Infrared Gas Analyzer Introduction

The infrared gas analyzer is capable of measuring the concentrations of NO, SO2, CO2, CO, CH4 and O2 components in sample gas. NO, SO2, CO2, CO and CH4 are measured by the non-dispersive infrared method (NDIR), while O2 is measured by built-in paramagnetic sensor or external zirconia sensor. A maximum of 5 components including O2 (up to 4 components except for O2 measurement) are simultaneously measurable.


The mass flow type twin detector of high sensitivity and reliability adopted in the infrared ray method detection unit makes the measurement hardly affected by interfering components. In addition, it has a large-size liquid crystal display, providing easy operation, high accuracy and multiple functions.

Infrared Gas Analyzer Feature

  • Ambient air temperature measurements at the optical path.


  • Temperature controlled optics and detector provide stable measurements—even in wide temperature fluctuations.


  • Precision optical components reduce sensitivity to contamination in dusty environments.


  • Scratch-resistant sapphire lenses for simple cleaning in the field.


  • High-performance brushless chopper motor provides dependable long-term operation.
