EMGA-920

Overview

EMGA-920 O/N analyzer: It's a "New flagship model” for O/N analyzers and user friendly product.

This is an oxygen and nitrogen 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 a non-dispersive infrared detector and the nitrogen by a thermal conductivity detector.


Manufactured by HORIBA
