Finally something that actually works! Tried many other devices and they did not work accurately or at all. This investment of $30 an incredible bargain for a quality device. After using mine I Purchased five of them for my relatives as Christmas gifts. Don’t be skeptical this is the real deal.

Great item! Very unique!

We are looking forward to being able to monitor our tank better now! Ordering was easy! Shipped quickly!


This is a very useful item for the patio. I do not think that we’ll suffer the frustration of our tasty ribeyes being 1/2 cooked running out of gas again.

I do not think we’ll end up with 1/2 cooked rib-eyes again. I love that my iPhone alerts me if we’re low or out of LPG.

About GasWatch

Propane Scale

GasWatch wants you to never run out of (grilling) gas again. It’s a digital propane tank monitor that keeps an eye on your tank’s level. And it’s Bluetooth-enabled to send updates to your phone, too.

The propane tank sits on the scale while it’s connected to your grill. It’s safer than other measuring methods because it works with closed tanks. And it can be kept outside, but it does need to be covered to protect it from rain and snow.

Keep track of the level on the digital display or through the app, which also has programmable cooking timer. The system is easy to integrate with your grill, and is a great way to make sure you never get caught with an empty tank.
