      IMPORTANT NOTE: 
            All performance data is based on conditions at 20°C, 50%RH and 1 atm, using City Technology recommended circuitry.
      Sensor performance is temperature dependant. For sensor performance at temperatures other than 20°C, please contact City Technology.
              Specifications are valid at 20°C, 50% RH and 1013 mBar, using City Technology recommended circuitry.
             Performance characteristics outline the performance of sensors supplied within the first 3 months.
              Output signal can drift below the lower limit over time.

      Poisoning
           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.

      Cross Sensitivity Table
             Whilst CiTiceLs are designed to be highly specific to the gas they are intended to measure, they will still respond to some degree to various other gases. The table below is not exclusive and other gases not included in the table may still cause a sensor to react.
            IMPORTANT NOTE : The cross sensitivity data shown below does not form part of the product specification and is supplied for guidance only. Values quoted are based on tests conducted on a small number of sensors and any batch may show significant variation. For the most accurate measurements, an instrument should be calibrated using the gas under investigation.
