The Crowcon Gasman is a single gas detector with a choice of sensors, including Combustible, Toxic and Oxygen. Compact and designed for use in harsh environments. Data and event logging are included on all models. A Carbon Dioxide instrument measuring 0-5% using an infrared sensor is also available, for use in safe areas only.
Toxic gas and oxygen versions are available in rechargeable and non-rechargeable variants. The flammable gas models are rechargeable only. The Gasman is the perfect choice for detecting specific gases with a monitor that can be serviced to extend its lifetime. Equipped with loud and bright alarms built in an unobtrusive compact and lightweight design. Single-button operation minimises training time.
Suitable for use in a range of industries including oil and gas, chemical plants (exotic gases), steelworks (CO compensated sensor) hospitality (CO2) and the water industry.
