a. The segment code display mode is clear and intuitive, and the operation of the instrument is easy and convenient;
b. Sensors in all components are originally imported, and they have a rapid response speed, high measurement accuracy, excellent linearity, long calibration cycle and stable performance, also the sensor can be changed when reaching its service life;
c. In explosion-proof occasions, the menu can be set by isolated-type magnetic pen, which is convenient for on-site operation;
d. The menu lock function could prevent mis-operation, which may change instrument parameters and affect its performance;
e. Automatic temperature compensation could eliminate the impact of environment temperature changes on the measured value;
f. The instrument allows multi-point fractional liner calibration, meeting the need for an accurate measurement of gas concentration among the full range.
g. The gas path of the measured cavity is designed specially with a polymeric membrane attached, which could effectively prevent fluid or interference media affecting the sensor.
