Dial gauge

If you are joining the trend or already experienced in food preservation, start by checking your equipment and supplies. Proper equipment in good condition is required for safe, high-quality, home-canned food.

It is recommended to test a dial gauge pressure canner for accuracy each year. If a dial gauge is out of calibration then there is a risk of under-processing food. Weighted gauge canners are meant to maintain accuracy over time and do not need to be tested.

The N.C. Cooperative Extension of Swain County will test your pressure gauge canner for free. Due to COVID-19, we request that you schedule an appointment on Tuesday, July 21, 2020, between 9 a.m. and 2 p.m. Please bring the lid only, the pot is not necessary. Then the lid will be tested, sanitized, and returned to you.

Please call (828) 488-3848 or email Dee Decker at to schedule an appointment.
