Record the calibration logs, repair logs, failure history, failure countermeasure solutions, sensor service life due reminder, and function of reminder for the time of next concentration calibration.
Mis-operation recognition function: automatic recognition and prevention of the concentration calibration mis-operation, which is possible to avoid the poor performance that may be caused by human factors. Zero-point automatic tracking; long-term use will not be affected by the zero drift. Multi-level calibration for target points, can ensure the linearity and accuracy of the measurements.
