Audited Supplier
a. Menu can be switched between Chinese and English and the operation is intuitive and convenient;
b. Dot-matrix liquid crystal display with big screen makes it possible to display parameters of oxygen content, date, time, etc.;
c. The original imported zirconia sensor consumes no service life when the power is off, and has a high measurement accuracy, rapid response speed and small zero drift value, etc.;
d. Automatic temperature and pressure compensation could reduce the impact of environment temperature and pressure changes on the measured accuracy;
e. The instrument allows multi-point fractional liner calibration, meeting the need for an accurate measurement of oxygen content among the full range;
f. Factory default settings can be restored, preventing analyzer parameters setting chaos resulted by mis-operation;
g. 5000 pieces of historical data can be stored automatically, enabling user to read historical data freely;
h. Upper and lower alarm limit can be set among the full range;
i. 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.
