Check the gas level easily: Now you will no longer be caught cold by a suddenly empty gas tank. You attach the magnetic indicator to commercially available gas cylinders and at a glance you know how much gas is left in it.
Ideal for butane or propane gas: The indicator reacts very sensitively to the temperature differences that occur in the bottle and thus determines the current gas level. You can read this on a precise, 22-step scale.
Note: The level of the gas cylinders can only be read accurately after use, virtually after the gas has cooled down.
