FN101B Portable Trace Oxygen Analyzer is a new-type intelligent industrial portable analyzer researched and developed by combining imported high-performance electrochemical sensor with new microcomputer technology based on the principles of electrochemical detection.

Application fields:

Quick analysis on trace oxygen in protective gases for high-temperature sintering furnaces of nitrogen production by air separation, chemical process, magnetic materials, and so on; in protective gases for electronic industry; and in glass and building material industries, as well as various gas mixtures

Instrument characteristics:

Imported fuel cell sensor adopted, featuring long service life, high accuracy, and quick response and immune to the interference of other gas components;

Automatic temperature compensation, eliminating the affect from ambient temperature;

128×64 lattice OLED display, able to simultaneously display parameters like oxygen content, date, and time;

Timed automatic storing function, and stored data available for viewing at any time;

Automatic range shifting; alarm point can be set at will within the whole range;

AC/DC power supply and flexible operation; built-in lithium-ion battery available for continuous operation of approximately 15 hours once fully charged; automatic alarm in case of low battery voltage;

Applicable for quick detection of trace oxygen in reducing gases, such as high-purity hydrogen;

Built-in air extracting pump and external filter can be added upon selection.
