Dial Gauge Canner Testing

Dial gauge pressure canners use dial gauges to indicate if the correct pressure is being maintained while canning. For accuracy before use, it is recommended that dial gauges get tested each year. Gauges that read incorrectly cause over- or under-processing and can result in unsafe food.

The Extension Green County office offers free dial gauge canner testing. Please call 608-328-9440 for more information.
