836 Series

Oxygen/Nitrogen/Hydrogen by Inert Gas Fusion Infrared and Thermal Conductivity Detection

The ONH836 Oxygen/Nitrogen/Hydrogen Elemental Analyzer is designed for wide-range measurement of oxygen, nitrogen, and hydrogen content of inorganic materials, ferrous and nonferrous alloys, and refractory materials using the inert gas fusion technique.

The instrument features a custom MS Windows®-based software interface designed specifically for touch-screen operation. Developed by combining long-term research with customer feedback, this easy-to-use software gives you complete access to instrument control, analysis settings, diagnostics, reporting, and more—without sacrificing valuable bench space.

Cornerstone® Mobile  option provides access to data, plots, and instrument status from your smart phone, tablet, or desktop computer.
