oxygen analyzer

oxygen analyzerInstrument features:

1. Reliable sample extraction unit

Pulse furnace power control heating, temperature can reach 3000 ℃.

Multiple program heating methods: constant power heating, slope heating.

2. Oxygen analysis uses a non dispersive infrared detection system, while nitrogen and hydrogen analysis uses a high-precision thermal conductivity detection system.

3. Using thermal extraction analysis technology, the residual hydrogen in the sample is determined by heating it at a temperature below the melting point, and the same instrument is used to analyze the oxygen, nitrogen, and hydrogen in solid inorganic substances.

oxygen analyzerModular detection unit:

Steel Research Nanok Oxygen Nitrogen Hydrogen Analyzer is a Chinese manufacturer of oxygen nitrogen hydrogen analyzers. In 1977, a vacuum melting gas analyzer was developed, and in 1991, a pulse infrared oxygen analyzer was industrialized here, breaking the foreign monopoly. Through 40 years of technological deposition, the Steel Research Nanogram Oxygen Nitrogen Hydrogen Analyzer has reached a level of proficiency.

The ONH-3000 oxygen nitrogen hydrogen analyzer adopts pulse heating and infrared thermal conductivity detection technology, which can achieve rapid and accurate determination of oxygen, nitrogen, and hydrogen elements in solid inorganic materials such as steel, metal powder, non-ferrous metals, ceramics, minerals, etc. across the full range.
