1 – Due to a very high cross sensitivity to Hydrogen Sulfide, this sensor is unsuitable for use in atmospheres that contain Hydrogen Sulfide
2 – CAUTION! Negative cross sensitivities may cause the sensor to produce lower readings than the true concentration of gas in ambient air.


Technical Note: TN-114 – Sensor Specifications and Cross Sensitivities for Hydrogen Cyanide 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.
