7、TiceL Specification Cross-sensitivity Data CiTiceLs may exhibit a response to certain gases in a sample other than the target gas. 7NDH CiTiceLs have been tested with a number of commonly cross-interfering gases and the results are given below. The table shows the typical response to be expected fro
8、m a sensor when exposed to a given test gas concentration (relevant to safety, e.g. TLV levels). Gas Conc. 7NDH Gas Conc. 7NDH Carbon monoxide: 300ppm 0ppm Hydrogen: 100ppm 0ppm Hydrogen sulphide: 15ppm -1.5 x 0ppm Hydrogen cyanide: 10ppm 0ppm Sulphur dioxide: 5ppm -0.05 x 0ppm Hydrogen chloride: 5p
