The return of BBQ season means that we will be playing the Guess how much propane is left in your tank game again. If the scenario of half cooked steaks because you ran out of propane mid-way keeps you up at night, do yourself a favour and pick up a Propane Gauge. Fitting between the tank and the barbecue hose, the gauge will tell you just how much propane you still have and when you have to get the tank refilled. No more guesswork!
The Propane Gauge comes with a leak detector and a positive seal mechanism that will prevent any gas flow until everything is properly connected.
The Propane Gauge is available for $24.96 USD directly from Brookstone.
