Dial gauge pressure canners are delicate instruments that can become inaccurate over time due to moisture and/or rough handling. This problem often goes undetected which is why it is suggested that all dial gauges be tested yearly for accuracy and overall condition. Individuals interested in having their canner dial gauge tested are invited to bring their gauges to ISU Extension and Outreach Lee County in Donnellson on the last Wednesday of every month starting in May and ending in August between 8:00 am and 4:00 pm. There is no charge for this service. No registration is required. Weighted gauges do not need to be tested as they are always accurate if used correctly. For questions please contact the Lee County Extension Office at 319-835-5116.
