Do not remove label.Adequate free volume should be provided below the sensor to ensure full performance. All tolerances ?0.15 mm unless otherwise stated. DO NOT solder to pins.All performance data is based on conditions at 20oC, 50% RH and 1013 mbar. General purpose, portable or fixed life safety. CiTiceLs are designed for operation in a wide range of environments and harsh conditions. However it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting ——————————————————————————————————————————————— into instruments, and operation. When using sensors with printed circuit boards (PCBs), degreasing agents should be used before the sensor is fitted. Do not glue directly on or near the CiTiceL as the solvent may cause crazing of the plastic. Toxic gases at TLV levels will have no cross-sensitivity effect on Oxygen CiTiceLs. At very high levels (i.e. percent levels), highly oxidising gases (e.g. ozone, chlorine) will interfere to the extent of their oxygen equivalent, but most other commonly occurring gases will have no effect. IMPORTANT NOTE: Acid gases such as CO2 and SO2 will be absorbed by the electrolyte and tend to increase the flux of oxygen to the electrode. This gives an enhanced oxygen signal of approximately 0.3% of signal per 1% CO2. Oxygen CiTiceLs are not suitable for continuous operation in concentrations of CO2 above 25%. SAFETY NOTE in which it is used, are operating properly, it is a requirement that the function of the device is confirmed by exposure to target gas (bump check) before each use of the sensor and/or instrument. Failure to carry out such tests may jeopardize the safety of people and property. Every effort has been made to ensure the accuracy of this document at the time of printing.
