Explosion-Proof Gas Analyzer - 51 Series

HORIBA’s 51 Series of explosion-proof analyzers enable accurate, reliable, and safe measurements during the analysis of flammable gases or while operating in hazardous environments. The 51 Series is in compliance with IEC 60079. The 51 Series explosion-proof infrared analyzers enable the measurement of CH4, CO2, CO, and other organic gases. The TCA-51 is equipped with a thermal conductivity detector for the measurement of H2, and the PMA-51 and MPA-51 models combine paramagnetic and magneto-pneumatic detectors for the measurement of O2.

The 51 Series explosion-proof infrared analyzers


  • Explosion-Proof Models for Flammable and Explosive Classified Areas
    The 51 Series has been authorized for use in flammable and explosive environments in Japan, which also meets international IEC standards.
  • Self-Diagnosis Function
    For ensuring stable analyses of gases, a self-diagnosis function is triggered upon detecting an abnormal condition. Execution of a management function provides the calibration factor records and regulates auto-calibration.
  • Reliable Analysis
    A compensating or correction detector prevents gases from interfering with the gas that is measured.
  • LED Display
    The 51 Series LED display is clearly visible, thereby enabling operators to easily view the status of the analyzer.
