Pressure Canner Dial Gauge Testing
A pressure canner is necessary for canning low-acid vegetables, meats, fish and poultry. There are two types of pressure canners: dial gauge and weighted gauge. Dial gauges on pressure canners should be tested annually for accuracy before use.
Gauges that read high cause under-processing and may result in unsafe food. Low readings cause over-processing. Pressure adjustments can be made if the gauge reads up to 2 pounds high or low. Gauges that differ by more than 2 pounds should be replaced.
Testing is free and takes only a few minutes. Schedule your appointment with UT Extension Marshall County below or contact 931-359-1929. Bring the lid and gauge to your canner with you.
