Canner Lid Testing

Canning season is right around the corner! Canners need to be tested every year for safe processing before canning season starts. This is an opportunity for you to bring your canner lid to have it tested. The N.C. Cooperative Extension, Forsyth Center offers free dial gauge pressure canner testing. All you need to bring is the lid of your pressure canner with the gauge attached. The testing process takes less than 10 minutes per lid.

Brands that can be tested:

  • Presto
  • Maid of Honor
  • National Magic Seal
Other brands cannot be tested since we do not have specific information on the gauges and their calibration. Please contact the manufacturing company for assistance with other brands not included here.
