Don't Let Your Gauge Be the Reason Your Canning Fails

Get your Pressure Canner Dial Gauge Tested

Before using your pressure canner, have your dial gauge tested for accuracy. Testing will ensure your pressure canner reaches the appropriate pressure needed to process low-acid foods, such as vegetables and meats, safely. Over time, a pressure canner's dial gauge will become inaccurate, resulting in either reading too high or too low.

Testing is offered at Jo Daviess, Stephenson and Winnebago County Extension Offices. To schedule an appointment to get your Pressure Canner Dial Gauge tested, call the office nearest to you:
