a. The instrument is small and easy to maintain;
b. The imported new-type zirconia sensor has a long service life, high sensitivity and rapid response speed;
c. There are N2and O2 types of display mode, and N2 displays in (N2%=100-O2%);
d. Automatic temperature compensation could eliminate the impact of environment temperature changes on the measured value;
e. Upper and lower alarm limit can be set among the full range;
f. The instrument allows multi-point fractional liner calibration, meeting the need for an accurate measurement of gas concentration among the full range.
g. Built-in standard RS485 communication port allows a unidirectional or bidirectional communication with computer or other digital communication equipment.
