Instrument Features:

a.  Chinese and English menu switching function, intuitive and convenient operation; 

b.   320×240 graphic dot matrix color LCD display, the display is delicate and clear; 

c.   The imported fuel cell sensor is used, which has the advantages of fast response speed, high measurement Features of strong anti-interference ability; 

d.   Gas circuit blockage alarm and self-protection function, automatically shut down sampling pump in case of gas circuit failure, effectively prolonging the service life of sampling pump and sensor; 

e.   Over-range protection function, when the oxygen concentration is higher than the protection function When the concentration is high, the gas circuit will be automatically cut off to avoid affecting its life due to the long-term exposure of the sensor in an environment with high oxygen concentration; 

f.   Automatic temperature compensation function, reducing the impact of temperature changes on the measurement accuracy; 

g.   The instrument supports multi-point separation Segment linear calibration to meet the accurate measurement of oxygen content in the full range; 

h.   40,000 pieces of historical data are automatically stored, and users can check historical data locally at any time; 

i.   Built-in imported sampling pump (pumping type), reliable and easy to use Long service life;

j.   According to user needs, optional RS232 (default) or RS485 data communication interface can be used for direct one-way or two-way communication with computer or other digital communication equipment.
