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.
