     If you have a pressure canner with a gauge, the Master Food Preservers at CCE Dutchess County can test it to see if it is still accurate.

Dial Gauges should be checked annually and CCE Master Preservers will check yours for FREE.

Just bring in the lid and gauge for testing - you may bring the entire pressure canner for inspection as well. Call or email to coordinate a time to drop off your equipment for testing and inspection.

Additional Pressure Canner Gauge Testing Resources:

     For National Presto canners with the “dial type” gauge, call their customer service number at 1-800-877-0441 (M – F, 9 am – 5:15 pm Eastern Time).  They will answer questions about free gauge testing and/or replacement.  
      Ship the gauge to:
      Consumer Service Department

      Eau Clair, WI 54703
