Portable Crowcon Gasman Detector (Rechargeable)

Designed to provide safety to a user in a hazardous environment, this Portable Crowcon Gasman Detector (Rechargeable) is a reliable safety solution.

This portable gas detector offers a variety of single gas configurations, allowing the user to tailor the device to their specific requirements. Ideally suited for oil and gas industry work, this rechargeable Gasman unit provides the user with resistance against dust and water.

Included is a large LCD backlit user display that makes it easy to read the gas concentration levels and battery life, in addition to visual, audible and vibrating alarms (vivid red/ blue visual warning are displayed). Data and event logging are provided as a standard, along with a preemptive 30 day warning when your next calibration is due.

See available spare and accessories below for items that are compatible with the Crowcon Gasman series.

NOTE: The rechargeable variants require a compatible charger, which is sold seperately (see below).
