Oxygen/Nitrogen/Hydrogen Combustion Analyzer | EMGA-930


EMGA-930 O/N/H analyzer: It’s a "New flagship model” for O/N/H analyzers and user friendly product.

This is a simultaneous oxygen, nitrogen & hydrogen elemental analyzer with high accuracy and repeatability suiting to cutting-edge technology’s R&D as well as quality control in the market of steel, new materials, catalyst and so on. This is a new generation model optimized to fit to user’s requests.

The oxygen is measured as carbon monoxide and carbon dioxide by two non-dispersive infrared detectors, the nitrogen by a thermal conductivity detector and the hydrogen with non dispersive Infra Red detector as H2O.


  • Super High Performance
  • User-friendly software
  • Fully Supported Accessories give simple operation
  • Improved Mechanism
  • Dual Sample/Flux introduction mechanism
