What’s the difference between dial gauges and weighted gauges?

Choosing Between Dial Gauges and Weighted Gauges

When it comes to canning pressure meat, accuracy is crucial to ensure safe and successful canning. Dial gauges are popular among canners due to their ease of use and quick pressure readings. However, their accuracy can be compromised if the gauge is damaged, worn out, or not calibrated correctly. Dial gauges typically require a 3-5% variation in pressure reading accuracy.

Weighted Gauges: A More Accurate Option

Weighted gauges, on the other hand, use the weight of a liquid column to measure pressure. This method provides more accurate readings, with a typical variation of 1-2% in pressure measurement. Weighted gauges are often preferred by experienced canners who require precise control over pressure levels. However, they can be more cumbersome to use and require regular calibration to ensure accuracy.

Practical Considerations for Canners

When selecting a gauge for canning pressure meat, consider the type of equipment you’re using. If you’re using a dial gauge, ensure it’s calibrated correctly and inspect it regularly for signs of wear or damage. If you opt for a weighted gauge, be prepared to invest more time in calibration and maintenance. Regardless of the gauge type, always follow safe canning practices and consult your equipment’s manufacturer guidelines for specific pressure levels and requirements.
