Cross sensitivity data was developed by exposure of sensors to gas concentrations below 100 PPM. Sensors may show either
transient or continuous responses different from those listed above if exposed to very high concentrations of gas. The values
shown are the equivalent signal generated by the sensor when exposed to 1 PPM of the indicated gas. For instance, exposure
of a chlorine (oxidant) sensor to 1 PPM of nitrogen dioxide would produce a sensor signal equivalent to 0.2 PPM chlorine.
Negative numbers indicate gases that can cause low readings when present with the target gas
* Indicates a three electrode sensor that requires a minimum of 5% oxygen for proper operation.
** Data shown for the chlorine sensor refers to the sensor used for bromine, chlorine, chlorine dioxide, fluorine or ozone.
Oxygen sensors will respond to halogen gases at % levels but are unaffected by low PPM levels.
Oxygen sensor response will be affected by % levels of CO2 but unaffected by low PPM levels.
