Description: The GasCheck allows the fill level of steel LPG cylinders (5 kg/11 kg) to be quickly determined. The device is simply pressed against the outside of the cylinder to be checked. Coloured visual and acoustic signals indicate the level. Users thus have a good indication of whether there is enough gas in the cylinder for their requirements or whether a second cylinder is required. Typical application areas are camping, BBQs, radiant heaters or working with gas burners.
