Butane / Propane Magnetic Gas Level Indicator

Have you ever been caught short with an empty gas cylinder? I know I have!

There is no way of telling how much is left and it can easily run out halfway through a barbecue or much worse on a chilly winters day when you're using your gas heater. Just place the magnetic indicator on the bottom half of the cylinder and once the gas is switched on, the colour of the bar will change and tell you how much gas is left.

Don't be caught short again!
