Pressure Canning Dial Gauge Testing

Did you know that you should test your pressure dial gauge every year, prior to the canning season? In addition to having your pressure dial gauge checked for accuracy, it should also be checked if any of the following conditions exist: cover has been submerged in water or dropped, gauge lens is broken or has fallen out, parts are rusty, pointer is not on “0”, or for any reason you believe the gauge may not be accurate.

If you would like to have your dial gauge tested, there is no cost for the testing. You will only have to pay the cost of shipping. Presto will return the gauge in a timely manner via FedEx, free of charge. Be sure to pack the gauge well in bubble wrap or newspaper and include your name, address (no PO Box, as FedEx only delivers to numbered addresses), and phone number on a piece of paper inside the box. Mail to:
