General Specifications Model IR100 Universal Infrared Gas Analyzer GENERAL Model IR100 is an intelligent universal infrared gas analyzer for CO2, CO and CH4. The analyzer is easy to maintain and works steadily over long periods. The ideal application of this analyzer is continuous measurement for the control and monitoring of combustion in various industrial furnaces as well as continuous measurement for the study of plants. FEATURES 1) Two available models The IR100TA and IR100A, dedicated for analysis of either CO2, CO, or CH4, IR100TB and the IR100B, dedicated for simultaneous analysis of CO2 and CO, are available. The minimum measuring range for each gas is described below. CO2: 0 to 500 ppm CO: 0 to 500 ppm CH4: 0 to 1000 ppm 2) Stable operation over long periods A special optical system reduces drift, which is usually caused by dirt on the measurement cell; therefore, the analyzer operates stably over long periods. 3) Influenced less by presence of another interfering gas A two-layer serial infrared transmission system minimizes influence by another interfering gas, for example, the vapor content in the object gas. 4) Easy maintenance Maintenance of this instrument is easy since the analyzer can be easily separated into several basic units. Optical balance adjustment is also unnecessary. 5) Wide variety of additional functions a) Self-diagnosis: indicates error code to notify the operato of an abnormality. b) Simple calibration: allows the operator to perform zero- and span-calibration by only pressing the calibration key while the reference gas is flowing. *c) Automatic calibration: automatically performs zeroand span-calibrations periodically at predefined intervals.This function can calibrate CO2 and CO simultaneously. *d) Remote switching of the measuring range: allows a range to be switched to another range by transmitting signals from a distance. This function is available for each gas. *e) Range identification: outputs contact signals to identify the range which is being selected. These signals are output for each gas. Note: The functions marked with an asterisk (*) are optional.
