Pressure Canner Gauge Testing
Pressure canners with only a dial gauge need to be tested annually to ensure dial gauges are accurate. If your dial gauge is not accurate, it is not correctly reading pressure which may result in under or over processing and unsafe food.
UCCE Master Food Preservers of El Dorado, Amador/Calaveras and Tuolumne Counties have devices to test Presto Brand pressure canner gauges and offer free pressure gauge testing at our offices. Call the office nearest you to set up a drop off of your canner and you will reserve a phone call when it has been tested and is ready for pickup. Usually testing can be done within a week.
