Over time as canner lids are handled, bumped, or just used, the calibration of a dial gauge can become inaccurate. Even gauges on new canners and replacement gauges need tested before use. So bring it in for testing!


  • The gauge will be tested using calibrated equipment, and the entire process should take no longer than 5-10 minutes per gauge.
  • Bring your canner lid with gauge attached (you do not need to bring the whole canner).
  • Contact the Lane County Extension office with questions or accommodations.

Pressure Regulators:

It is also recommended that you convert your single weight to the 3 part weight for Presto canners. For All American it is a round weight that replaces the vent pipe with a petcock. It has 3 holes for 5lb, 10lb and 15lb pressure. Weights never need to be calibrated, and the gauge becomes an indicator when you can safely remove the lid. Please contact the manufacturer below to ensure you order the correct one.
