*Operating time will depend on operating pattern and alarm occurrence. Frequent or long lasting alarms and use of the optional confidence beep will reduce battery life.
**Toxic and oxygen sensors are not rated for continuous operation at high temperatures. Consult Crowcon if operating temperatures are likely to exceed 40°C (104°F) for extended periods.
Gases and Ranges
Required ranges and alarms vary by country and application and these can be configured as required. Each gas channel can have two instantaneous alarm levels set. Toxic units also have Time Weighted Average (TWA) alarms.
Flammable gas calibration is available for methane, propane, butane, pentane, hydrogen and
ethylene as standard.
Gasman is also available in a safe area CO2 version offering 0-5% carbon dioxide measurement.
