Appendix A Sensor Cross-Sensitivity Chart

The table below provides the cross-sensitivity response of the ToxiPro toxic gas sensors to common interference gases. The values are ToxiPro as a percentage of the
primary sensitivity, or the reading of the sensor when exposed to 100ppm of the interfering gas at 20ºC. These values are approximate. The actual values depend on the
age and condition of the sensor. Sensors should always be calibrated to the primary gas type. Cross-sensitive gases should not be used as sensor calibration surrogates
without the written consent of Honeywell Analytics.
