Relative Sensitivity
The table below shows the variation in response of the CiTipeL on exposure to a range of gases and vapours atthe same %LEL concentration. The figures are experimentally derived and expressed relative to the methanesignal (=100). Testing was performed using 50%LEL CH 4 (based on 99%LEL CH 4 = 5%vol.)
Note: The results are intended for guidance only. For the most accurate measurements, an instrument should be calibrated using the gas under investigation.
Gas / Vapour | Relative Sensitivity* | Gas / Vapour
| Relative Sensitivity* |
Methane | 100 | Carbon monoxide | 120 |
Propane | 65 | Hydrogen | 110 |
n-Butane | 65 | Ammonia ** | 140 |
n-Pentane | 55 | Cyclohexane | 50 |
n-Hexane | 50 | Ethylene | 95 |
Acetylene | 90 | 1, 3-Butadiene | 60 |
* Each sensitivity has been rounded to the nearest 5%** T 90 for ammonia has been extended. Contact City Technology for further details. | |||
