FN3001B Zirconia Oxygen Analyzer is composed of an intelligent signal converter with microprocessor as its core and an imported zirconia detector and used for online detection of oxygen content in the gas detected.

Application fields:

Automatic analysis on oxygen content in nitrogen or argon in electric power, metallurgy, and air separation industries

Instrument characteristics:

Zirconia detector adopted, featuring long service life, stable performance, and quick response;

Wide measurement range, available for analysis from trace oxygen to macro oxygen;

128×64 lattice LCD, 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;

Standard RS232 or RS485 communication interface available for two-way communication with computer;

Alarm for out-of-control temperature;

Display switchable between oxygen content, potential value, and operating furnace temperature;

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