Place of Origin: Britain Brand Name: CITY Model Number: 5SF/F UK2F Features: CiTiceLs may exhibit a response to certain gases in a sample other than the target gas. The table below shows the typical response of 5SF sensors to a number of common cross-interfering gases. The figures are expressed as a percentage of the primary sensitivity (i.e. sulphur dioxide = 100%). Gas Response Gas Response Carbon monoxide: 3 Hydrogen: 3 Hydrogen sulphide: ?200 Hydrogen chloride: ?15 Nitric oxide: 0 Ethylene: 50 Nitrogen dioxide: ?-125 ** For details of other possible cross-interfering gases contact City Technology Specifications: Temperature Range -20C to +50C Pressure Range Atmospheric 10% Pressure Coefficient 0.004 % signal/mBar T90 Response Time 30 seconds Relative Humidity Range 15 to 90% non-condensing Typical Baseline Range 0 2ppm equivalent
