About Dial Gauge Testing
Dial gauge canners should be tested every year to ensure accurate pressure readings.
| Note: The Presto testing unit is used to test gauges for National, Magic Seal, Maid of Honor, and Presto brand canners only. The All American canner is a weighted gauge canner with a reference dial; do not use the Presto testing unit on an All American canner. |
