Relevant cross-sensitivities – DrägerSensor XXS HCN
The values given in the table are guide values and apply to new sensors. The values stated may vary by ±30%. The sensor may also be sensitive to other gases (data available from Dräger on request). Gas mixtures may be displayed as a combined total. Gases with a negative sensitivity can cancel out a positive HCN reading. It should therefore be checked whether gas mixtures are present.
| Gas/vapour | Concentration | Reading in ppm HCN |
|---|---|---|
| Acetylene (C2H2) | 100 ppm | ≤ 10 |
| Ammonia (NH3) | 50 ppm | no effect |
| Carbon monoxide (CO) | 200 ppm | no effect |
| Chlorine (Cl2) | 10 ppm | ≤ 20 (−) |
| Hydrogen (H2) | 1.5 vol.% | ≤ 10 |
| Sulphur dioxide (SO2) | 20 ppm | ≤ 10 |
