How often should sensors be re-calibrated?
The time period between initial calibration and successive re-calibrations depends on many factors, commonly the operating temperature/humidity/pressure in which the sensor is used, the gases it is exposed to and the length of time the sensor is exposed to gas. In general, however, CiTiceLs® provide very stable signals over time and for most applications, instruments containing CiTiceLs® would only require periodic calibration, often as little as once a year. In strenuous applications involving extremes of operation, or for sensors used in safety applications, more frequent instrument calibration may be required.
