LCD Display Infrared Gas Analyzer IR202 IR400 NDIR Type Measuring NO SO2 CO2 CO CH4 O2

Yokogawa Infrared Gas Analyzer IR202 IR400 NDIR Type Measuring NO, SO2, CO2, CO, CH4, O2

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.

This analyzer is a powerful tool for combustion control of various industrial furnaces, for botanical studies, and for global atmospheric research.

Features

• Simultaneous measurement of 4 components, including O2
• High stability for long periods
• Easy maintenance thanks to a single beam system for measurement
• Interactive operation on a large LCD screen
• Automatic calibration, self-diagnostics, and other useful functions

GENERAL

The IR202 infrared gas analyzer is capable of measuring concentration of CO2, CO, CH4, SO2, and NO components in sample gas by non-dispersive infrared method (NDIR), while measuring O2 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, low maintenance and an excellent stability are ensured for a long period of time. Microprocessor-based IR202 has a large-sized liquid crystal display, providing easy operation, high accuracy and multiple functions thus is optimum for measuring combustible gas, exhausted from boilers or incinerators.

FEATURES

1. Simultaneous gas measurement

Simultaneous gas measurement up to 4 components including O2 and 3 components selected from among CO2, CO, CH4, SO2, and NO.

2. Excellent long-term stability

A unique optics system minimizes drift particularly due to contamination of measurement cell, ensuring excellent long-term stability : zero stability ±0.5% or less FS/week.(IR202-C)

3. Low maintenance

Single beam system allows for simple measurement unit construction and requires no adjustment of optical balance, resulting in low maintenance.

4. Easy operation

Large LCD provides easy interactive operation.

5. Extensive functions

Highly precise zero/span calibration is achieved by simply pressing calibration keys. Automatic calibration is also available. Self-diagnostic function detects abnormality and displays an error massage. Other functions include remote range switching, range identification signal output, output signal hold, and upper/lower limit alarm.
