GASMAN

The Gasman is a compact, lightweight and highly durable single-gas detector, designed for use in the toughest environments. Perfect for customers who need more sensor options, TWA and data capability.

Where to Buy

Available with a choice of sensor technology to suit your needs, the Gasman is an ultra-lightweight single gas detector, designed for use in the toughest environments. Its compact and lightweight design makes it the ideal choice for industrial gas detection, in oil and gas, chemical plants (with exotic gases), steel works (special CO sensor), hospitality (CO₂), renewable energy (hydrogen) and waste and water works. Also available with our long-life O₂ sensor (LLO₂), for the accurate detection of oxygen depletion and enrichment, which comes with a 5 year warranty.

Weighing just 130g, it is extremely durable, with high impact resistance and dust/water ingress protection, loud 95 dB alarms, a vivid red/ blue visual warning, single-button control and an easy-to-read, backlit LCD display for clear insights and warnings. Data and event logging are available as standard, and there is a built-in 30-day advance warning when calibration is due. Gasman is also available in a safe area CO₂ version offering 0-5% carbon dioxide measurement.

*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.

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.
