Did you know that your pressure canner dial gauge needs to be checked for accuracy every year? To make sure that your canned foods are safe to eat, your gauge must be accurate. Like other mechanical devices these gauges can malfunction. They can also become inaccurate from the hazards of use, from being accidentally banged against something, or from storage where there has been exposure to extreme heat or cold during the off season.
Dial gauges can be tested by appointment at the OSU Extension Office in Washington County. Testing is performed on dial-gauge pressure canners only. Weighted gauges need not be tested.
Please call 740-376-7431 for an appointment to have your gauge tested or check. Bring your canner lid with gauge and gasket with you for the most thorough assessment.
