Toxic Sensor Cross-Sensitivity
IQ Force™ Gas Detector Reference Manual Appendix
Appendix D Toxic Sensor Cross-Sensitivity
The table below provides the cross-sensitivity response of the IQ Force toxic gas sensors to common interference gases. The values are expressed as a percentage of the primary sensitivity, or the reading of the sensor when exposed to 100 ppm of the interfering gas at C. 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.
