Using a layer of defense to detect against kegerator CO2 leaks…

Placing a CO2 Monitor with alarm inside of your kegerator can serve as another line of defense to protect against co2 leaks and loss. CO2 should not be building up in your kegerator. A CO2 monitor with alarm can alert you of this condition.

This is not a replacement for checking for CO2 leaks using traditional methods, rather a another layer that could save you a trip to swap out a CO2 tank.
