Quick Answer
A dial gauge is the best type of gauge for pressure canners as it provides an accurate reading of the pressure inside the canner.
Choosing the Right Pressure Gauge
When selecting a pressure gauge for your pressure canner, look for a dial gauge specifically designed for canning. A dial gauge is more accurate than a weighted gauge and provides a precise reading of the pressure inside the canner. It’s essential to choose a gauge that is calibrated for the specific altitude at which you are canning, as altitude can affect pressure.
Dial Gauge Accuracy and Calibration
A dial gauge is typically accurate to within 1-2 pounds of pressure. To ensure accuracy, make sure to calibrate your gauge according to the manufacturer’s instructions and the altitude at which you are canning. It’s also essential to understand that a dial gauge should show a consistent reading as the pressure increases or decreases, and that the needle should move smoothly and steadily.
Important Safety Considerations
When using a pressure gauge, it’s crucial to understand that the gauge is an essential safety component of your pressure canner. Always follow the manufacturer’s instructions for the gauge and the pressure canner, and never use a gauge that is damaged or malfunctioning. The gauge should be easily readable, and the needle should move smoothly and steadily as the pressure increases or decreases. If you’re unsure about the accuracy or functionality of your gauge, it’s best to err on the side of caution and replace it with a new one.
