IR200 NDIR Type Infrared Gas Analyzer

Brand: Yokogawa Electric Corporation

The IR200 infrared gas analyzer is capable of measuring the concentrations of CO₂, CO, CH₄, SO₂, NO and O₂ components in sample gas.

CO₂, CO, CH₄, SO₂ and NO are measured by nondispersive infrared method (NDIR), while O₂ is measured by paramagnetic or zirconia method.

A maximum of 4 components including O₂ (up to 3 components except for O₂ measurement) are simultaneously measurable.

A high-sensitivity mass flow sensor is adopted in the detection unit for the infrared method.

Due to use of single beam system for measurement, maintenance is easy and an excellent stability is ensured for a long period of time.

In addition, the IR200 and has a large-size liquid crystal display, providing easy operation, high accuracy and multiple functions.
Features
  • Simultaneous measurement of 4 components including O2
  • Excellent long-term stability
  • Subdued interference from other gas components
  • Easy to maintain
