Non-Dispersive Infrared Gas Analyzers (NDIR) IR100

2016-05-26 15:36:27


The IR100TA and IR100A, dedicated for analysis of either CO2, CO, or CH4, the IR100TB and the IR100B, dedicated for simultaneous analysis of CO2 and CO, are available. The analyzers are easy to maintain and works steadily over long periods. The ideal application of these analyzers are continuous measurement for the control and monitoring of combustion in various industrial furnaces as well as continuous measurement for the study of plants.……




  • Two available models: simultaneous dual-gas (CO and CO2) measurement model and single-gas dual-range measurement model

  • Stable operation over long periods

  • Influenced less by presence of another interfering gas

  • Easy maintenance

  • Wide variety of additional functions: self-diagnosis, simple calibration, automatic calibration, remote switching of the measuring range, and range identification
