Master Preservers

Have questions about home food preservation?

Our Home Food Preservation Consultation Experts will answer them for you!

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 Dutchess County 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. 

Direct your questions to Subject: "Food Preservation" and you will receive a follow up email. To schedule lid and gauge testing, email with the subject: "Canner Inspection Request".

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:
