HY-OPTIMA™ 2700 Series Operating Manual Chapter 5: Supplemental Information and Troubleshooting 5.1 Storage Note: Oxidation effects are not applicable to the model 2720 as it is designed to operate in air. 5.1.1 Storage Oxidation & Offsets Analyzer readings will develop an offset when the sensor element is not exposed to hydrogen. This offset accumulates slowly while the sensor is in storage, and quickly while the sensor is powered on without being exposed to hydrogen. -
Page 38: Avoiding A Storage Oxidation Offset
H2scan recommends this approach whenever it is feasible. For a fee, H2scan will keep a customer’s backup analyzers continuously powered on in hydrogen gas at our calibration facility, and ship out the fully conditioned backup sensor when it is needed. -
