Description
Overview
GAOTek single portable gas detector is a kind of mini size and high accuracy portable multi gas detector. Easy to operate, comprehensive functions, can measure 4 common gas hazards: carbon monoxide, hydrogen sulphide, flammable gases and oxygen depletion, other multi gases are available for customization. The detector has a back clip, protected by a silicone case, suitable for different kinds of situations.
