General Introduction
Yokogawa IR400 Infrared Gas Analyzer measure concentration 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, the IR400 has a large-size liquid crystal display, providing easy operation, high accuracy and multiple functions. Optimum as an analyzer unit of measurement system for combustion exhaust gas from refuse incinerator and boiler, or gas from different industrial furnaces.
