Outset F600 Propane Tank Gauge

Why don't propane tanks come with a built-in gauge telling you how much gas is left in the tank? Outset can't answer that, but they can provide you with a handy little gadget to help. This gas gauge fits propane tanks and appliances with a Type 1 connection and includes a built-in leak detector so you can keep on top of not just your supply, but your safety. Don't get caught running out of fuel again.
