You no longer need to guess if the propane is about to run out while you are cooking or grilling. This smart indicator works by measuring the temperature differences on the cylinder wall, showing you the exact level point with clear colors. Simply place it on the lower half of the bottle and watch the gas flow being displayed live.

Forget about complex electronic systems and batteries that run out quickly. Its magnetic base allows you to remove it with one motion as soon as the bottle is empty and stick it immediately to the next full one. The liquid crystal technology it incorporates responds instantly when your device is in operation, offering you a reliable solution for every use.
