  • ONH-2018 Series Oxygen Nitrogen Hydrogen Analyzers are professional laboratory analytical instrument with high sensitivity, high precision and high stability. Due to the modular design, future hardware and software upgrades are convenient. it is used to analyze oxygen, nitrogen and hydrogen concentrations in inorganic sample materials reliably, accurately and safely by inert gas fusion.


  • The ONH-2018 series Oxygen Nitrogen Hydrogen Analyzers are used to analyze oxygen, nitrogen and hydrogen concentrations in inorganic sample materials reliably, accurately and safely by inert gas fusion. Determination of oxygen, nitrogen and hydrogen in Iron, Steel, Cobalt, Nickel, Ferroalloys, Copper Production,Titanium, Zirconium and other Refractory Metals, Metal Processing, Aluminum and Magnesium, Magnetic Materials. For example, Determining the amount of oxygen and nitrogen is critical during the steel making process, the final alloy adjustment by addition of ferroalloy but also for the production of nickel- and cobalt-base alloys.


  • 1. Digital closed-loop control pulse electrode furnace

    2. Powerful 8.0KW impulse furnace for temperatures in excess of 3000℃
