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 at the OSU Extension Office in Washington County. Testing is performed on dial-gauge pressure canners only. Weighted gauges need not be tested. If a qualified staff member is available, the testing can be done while you wait. Otherwise, you can make an appointment, or you can leave the gauge to be tested and we'll call you when testing is complete. Bring your canner lid with gauge and gasket with you for the most thorough assessment.
Please call 740-376-7431with any questions.
