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.
