Only Presto canners with a dial gauge or old All Americans with a non-removable petcock need to be tested annually to ensure the dial gauge is accurate. All others are weighted gauges and do not need to be tested. The Presto gauge test kit is designed for Presto gauges only. If your dial gauge is not accurate, it is not correctly reading pressure which may result in under or over processing and unsafe food.

Please Note: the only pressure canner that needs to have its dial gauge tested is a Presto. (The others are all weighted gauge canners and only need the dial gauge to tell when the pressure drops to 0.)  You can easily convert your dial-gauge Presto pressure canner to a weighted gauge by swapping out the deadweight for a 3-piece weighted regulator.

Here’s the link to the 3-piece weighted regulator sold by Presto: https://www.gopresto.com/product/pressure-canner-pressure-regulator-50332. This way you don’t need to worry about checking the dial gauge, you can use the canner as a weighted gauge canner.
