The Pierce County UW-Extension Office offers dial gauge testing, free of charge. The dial gauge is tested against a calibrated reference gauge to determine accuracy. Gauges testing +2 psi of the target pressure of 6 psi or 11 psi can be safely used at home.
To schedule an appointment to have your canner lid tested, please call the Pierce County UW-Extension Office at 715-273-6781. You can also drop your lid off, and we will test it and call you when it is ready to be picked up.
If you have any questions, please contact Katie Feuerhelm, Family Living Educator, at 715-273-6781 or firstname.lastname@example.org
