The purpose of this document is to present the performance specification of the 1 Series 1OX oxygen gas sensor. This document should be used in conjunction with the 1OX Characterization Note, the Operating Principles (OX09) and the Product Safety Datasheet (PSDS 5). To the best of City Technology’s knowledge, the data provided in this document is more suitable when the sensor is used at 20°C, 50% rH and 1013 mBar for 3 months from the date of sensor manufacture. For guidance on sensor performance outside of these limits, please refer to the 1OX Characterization Note. Output signal can drift below the lower limit over time. For guidance on the safe use of the sensor, please refer to the Operating Principles (OX09).
