Meet the Gaswatch: a digital tank scale that saves you from having to worry about running out of gas. Unlike old pressure gauges, there is no connection to the propane tank, so you don’t have to deal with any type of leakage. You just put your tank on the scale, select its weight on the display, and the scale does the rest. You can fit this scale inside your grill cabinet.
The Gaswatch is not expensive and can be set up easily. It displays cook time remaining and % of gas remaining in tank. It can provide you with low gas level alarms too! What do you think? Are you impressed?
