Pressure Canner Types

There are two types of pressure canners – weighted gauge and dial gauge.

Weighted gauges do not need to be tested. Just make sure to check rubber seals and safety plugs regularly for wear and replace when necessary.

Dial gauge canners have a sensitive pressure gauge used to measure the internal pressure of the canner. As a delicate scientific instrument they can often be damaged or off to some degree.

If the dial gauge on your pressure canner does not register correctly, you could be jeopardizing the safety of the food you preserve. To avoid any issues with the proper function of your pressure canner, you should have it checked.

The USDA recommends having pressure canner dial gauges tested annually.

Can you use a pressure canner as a hot water bath canner?

If you have a Presto brand pressure canner, you may be able to use it as a hot water bath canner as well. Here are the Instructions from Presto (pdf).
