Testing Dial Gauge Canners toolkit
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.

Follow these 6 Steps for Testing Dial Gauge Canners (available as a printable reference).
- Have the master gauge calibrated. Presto Industries (Eau Claire, WI; 715-839-2121) offers free calibration for master gauges. A sample letter requesting calibration services is available. Master gauges must be calibrated every year before use.
- Prepare dial gauge testing report form to use. The UW-Extension canner tester report must be used. A master copy of the form is here.
- Prepare the ‘Quick Tips for Safe Preserving’ for consumers and make copies. At the bottom of the page, include contact phone and email information for a local educator in case of follow-up questions. Please ask colleagues before listing their name and contact info! Colleagues may be able to assist, consult this map.
- Staff the service. Pressure canner gauge testing is under the supervision of a trained Extension educator/support staff or a trained volunteer. Individuals may have been trained in-person or they can review the Kansas State video here. Office staff who support testing are considered trained if they review the training video. Colleagues may be able to assist.
- Test dial gauges. Dial gauges on pressure canners should be tested each year against a calibrated ‘master’ gauge. Weighted gauges on canners are not tested, they do not go out of calibration. The All-American canner is a weighted gauge canner and should not be tested with the Presto gauge tester.
- Complete and sign the dial gauge report. Affix a sticker to the canner lid. The educator/staff doing the testing completes and signs the dial gauge canner testing report. The consumer must sign the report. Give the original copy of the report to the consumer and keep a second copy in the county office for 1 year, until the start of the next canning season.
A sticker with the results of the gauge testing must be placed directly on the canner lid or on the top of the dial-gauge housing. Sticker template using Avery 5160 return address labels is here.
Call Barb with questions 608-263-7383.
Note: Dial gauge canner testing units approved for use in county offices can be ordered from Presto.
