1、 Product Introduction
The NK-100 series oxygen analyzer adopts imported high-quality and high-performance oxygen sensors, which have fast response time and long service life, and can simultaneously meet the analysis and detection of percentage content, PPM, and PPB orders of magnitude. The instrument is designed for different gas environments and can be used for real-time measurement and analysis of oxygen concentration in pure gases, inert gases, and special atmospheres (acidic, alkaline environments). The instrument combines flow control, temperature compensation, and pressure control systems, providing a better human-machine operation platform and a wide range of usability.

2、 Application fields of oxygen analyzer
1) Air Separation Industry: Analysis of Oxygen Content in Nitrogen, Argon, and Inert Gases
2) Metallurgical Industry: Analysis of Oxygen Content in Blast Furnace Gas, Converter Gas, and Smelting Protection Gas
3) Petrochemical and biological fermentation: oxygen content analysis in specific process steps (such as oxygen analysis in electrolytic hydrogen, oxygen analysis in compost, etc.)
4) Semiconductor chip and electronic manufacturing industry: analysis of oxygen content in various protective soldering or protective gases
5) Food industry: Analysis of oxygen content in CO2
6) Coal chemical industry: analysis of oxygen content in coal gas, analysis of oxygen content in chemical workshops

3、 Characteristics of Oxygen Analyzer Products
1) Quickly and accurately analyze oxygen content; Standard 19 inch chassis/small disk mounted chassis/portable chassis, can be integrated with microcomputers and PLCs in a complete analysis system.
2) Highly versatile and suitable for multiple uses.
3) Suitable for online process analysis and portable analysis.
4) Power on self-test, stable operation, no maintenance required.
5) The sensor has a zero point and provides a zero output in an anaerobic environment without the need for zero point calibration gas.
6) Accurately measure from% to ppm level.
7) The application of diaphragm technology enables the analyzer to work stably for a long time in special atmospheres such as acidic and alkaline environments.
