    10 Maintenance and Calibration Checks 10.1Sensor Maintenance Servomex analyzers require no routine maintenance other than the occasional addition of Servomex Hummingbird Brand Replenishment Solution to the sensor. Exposure to dry gas samples will gradually extract liquid from the sensor. Under these conditions, the frequency of solution additions will be slightly higher.

    10.2Calibration All Servomex analyzers are calibrated with certified gas standards at the factory prior to shipment. No additional calibration is required before use. Depending on the application, the span calibration should be checked approximately every twelve months using a gas of known concentration and high quality plumbing components.

  • Page 55: Theory Of Operation

    11 Theory of Operation The Servomex Coulometric Sensor uses an ambient temperature oxygen reaction that is non-depleting. The cell produces a current flow that is determined by the number of oxygen molecules that are reduced at the cathode. The sensor reaction is driven by 1.3 Volts applied across the electrodes.

    As a result, if the analyzer is recalibrated at lower than normal flow rates, the new flow rate must be held within +/- 10%. The normal insensitivity of Servomex sensors to flow rate changes is the basis for the Flow Sensitivity Leak Check Method described in the section on Leaks found on page 38.
