IR202
The model IR202 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.
A maximum of 4 components including O2 (or up to 3 components without O2 measurement) are simultaneously measurable.
A high-sensitivity mass flow sensor is employed in the detection unit for the infrared method. A single beam system for measurement makes maintenance easy and ensures high stability for a long period of time. The microprocessor-based IR202 has a large liquid crystal display and features easy operation, high accuracy, and multiple functions that make it optimal for measuring combustible gas from boilers and incinerators.
By including this new product in the lineup, Yokogawa aims to capture a greater share of the gas analyzer market through solutions that improve plant efficiency and safety.
IR400
The IR400 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, 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.
