1 – Short exposure of <few minutes of <100 ppm with filters
2 – With onboard filters removed
3 – CAUTION! Negative cross sensitivities may cause the sensor to produce lower readings than the true concentration of gas in ambient air. Chlorine Dioxide sensors without on board filters have a negative cross sensitivity to hydrogen sulfide and other reducing gases and may underestimate the Chlorine Dioxide concentration if Hydrogen Sulfide is present.


Technical Note: TN-114 – Sensor Specifications and Cross Sensitivities for Chlorine Dioxide Replacement Sensor

Disclaimer: Technical Note TN-114 presents specifications, cross sensitivities and calibration information on select Rae Systems by Honeywell sensors. All specifications presented in this Technical Note reflect the performance of standalone sensors. For instrument specifications, please refer to product datasheets and manuals. Actual sensor characteristics may differ when the sensor is installed in different instruments. As sensor performance may change over time, specifications provided are for brand new sensors.
