Canning vacuum pressure gauges are designed to check the vacuum in a sealed can or jar. These gauges can be used on canned food and drinks.
The test is performed by pressing the needle of the gauge through the top of the can. The rubber gasket seals air from entering the can. The value is shown in Hg units.
Optional rubber cover provides a comfortable grip and impact protection.
