Infrared Gas Analyzer IR800G, IR810G

Responding to a Wide Range of Needs from Environmental Issues to Combustion Control
Simultaneous Measurement of Up to Five Components
In recent years, environmental measurement has become increasingly important from the perspective of SDGs and carbon neutrality, and measurement accuracy standards are becoming more stringent every year.
The IR800 series is the most suitable analyzer for CEMS (Continuous Emission Monitoring System) and can meet the environmental regulations of various countries. It can also be used to manage process combustion for efficient control.

Yokogawa has been selling gas analyzers for environmental measurement since 1971, and continues to develop and improve them based on its many years of experience and achievements. The highly reliable IR800 series contributes to environmentally conscious factories by making their operations easier to measure.
The IR800 infrared gas analyzer can measure concentrations O2 and up to 4 other components (NO, SO2, CO, CO2, CH4) in a sample gas using a non-dispersive infrared (NDIR) method. And as environmental regulations are becoming stricter, we have achieved stable measurement with less drift.

Our Active Zero-Drift Cancellation Mechanism achieves stable measurement of low concentrations, which are traditionally difficult to measure. It also includes Engineering/ASI functions—no need to add them separately.
