Free Gauge Testing

Test Your Dial-Gauge Pressure Canner

If you use a dial-gauge pressure canner, you should have the gauge tested annually to be sure the canner is reaching a safe pressure during canning. 

We can test Presto gauges free of charge in the Farm Advisor's Office in Bishop. Please call (760) 873-7854 or email us at immg@ucanr.edu to make an appointment.

All-American canners also have a dial gauge, however this canner is considered a weighted-gauge canner. The dial is there for convenience and information only. Due to the shape of the lid of All-American canners it is difficult to test these. If you have more questions about All-American canners' gauges please contact the manufacturer at https://www.allamericancanner.com/contact.htm 

Live out of our area? Other county MFP programs also offer this service. Here is a list of locations.
