a.   Friendly communication menu allows an intuitive and convenient operation;
b.   320×240 graphic dot-matrix color LCD display is clear to see;
c.   The original imported infrared sensor has a rapid response speed, high measurement accuracy, small zero drift value and long calibration cycle, etc.;
d.   The instrument allows multi-point fractional liner calibration, meeting the need for an accurate measurement of oxygen content among the full range;
e.   It is of excellent selectivity for measured gas, which could reduce the impact of cross interference; 
f.    Automatic temperature compensation function could reduce the impact of environmental temperature changes on the measurement accuracy;
g.   40 thousａnd pieces of historical data can be stored automatically, enabling user to read historical data freely;
h.   RS232 (default) or RS485 digital communication port can be selected according to clients’ requirement, to realize unidirectional or bidirectional communication with computer or other digital communication facilities.

It is used to monitor carbon monoxide allowance produced in combustion environment.
