Testing your pressure canner gauges is an important step to ensure food safety. Gauges can drift over time and give inaccurate pressure readings which may mean that your food has not been adequately processed for safety. Brand new gauges should also be tested to guarantee accuracy before they are used for the first time. Gauges can be tested free of charge at The Polk County Extension office.
The Polk County Extension office in Dallas offers free testing of pressure canner gauges. Please drop off your canner lid with the gauge attached (or the gauge only), at the Dallas office during regular office hours (weekdays from 8 am until 5 pm, excluding lunchtime noon until 1 pm). The gauge will be tested as time allows and you will be notified when it is ready to pick up. Please call the office at 503-623-8395 for more information.
