Extension recommends having your dial gauge pressure canner tested yearly for accuracy. It is important to know that the gauge is accurate in order to ensure food safety when canning food. Extension offices around the state offer dial gauge testing for free. To get in touch with your local office, call 877-520-5211. For more information on the care and keeping of pressure canners, take a look at this publication from the Pacific Northwest Extension, Using and Caring for Your Pressure Canner.
