The Crowcon Gasman is a personal gas detector, designed to detect a range of toxic gas, flammable gases and can detect carbon dioxide (CO2).

Weighing just 130g, The Gasman is extremely durable, with high impact resistance and IP65-rated dust/water ingress protected, a vivid red/ blue visual warning, single-button control and an easy-to-read, backlit LCD display to ensure clear viewing of gas level readings, alarm conditions, and battery life.

Datalogging and event logging are available with the Crowcon Gasman single gas detector.  This allows 900 hours to be stored at 1-minute intervals (54,000 logs), as well as more than 4800 events. Plus there is a built-in 30 day advance warning when calibration is due.
