Appendix D Toxic Sensor Cross-Sensitivity
The table below provides the cross-sensitivity response of the MultiPro 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 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 express written consent of Biosystems.
