Canners Gauge is used for testing vacuum of packaged products such as canned food or drink.
This gauge is easy to use for destructive sampling tests. Force the stainless steel needle through the top of the container while you read the gauge. The rubber gasket prevents air from entering the container during the test. 1” graduations in Hg are easy to read within the 2” diameter case. Stainless steel needle can be cleaned for multiple use, but is non-removable.
