DatasheetOverview
Gases include the most common four (carbon monoxide, methane, oxygen and hydrogen sulphide), but also an expanded range: ammonia, ozone, sulphur dioxide, H2 filtered CO (for steel plants) and IR carbon dioxide (for safe area use only).

Gases and Ranges
Ranges and alarms vary by country and application; these can be configured as required. Each channel can have two instantaneous alarms. Toxic channels also have TWA alarms. Flammable gas calibration is available for methane, propane, butane, pentane, hydrogen and ethylene as standard.
| Gas | Range | Typical Alarms |
| Flammable | 0-100% LEL | 20% LEL |
| Oxygen | 0-25% | 19/23.5% volume |
| Hydrogen sulphide (H2S) | 0-100ppm | 5ppm |
| Carbon monoxide (CO) | 1-500ppm | 30ppm |
| Sulpher dioxide (SO2) | 0-20ppm | 1ppm |
| Ozone (O3) | 0-1ppm | 0.1ppm |
| Ammonia (NH3) | 0-100ppm | 25ppm |
| *Carbon dioxide (CO2) | 0-5% | 0.5 % volume |
