While a pressure canner can also be used for cooking these various foods, it is usually much larger and is designed to be used for home canning of foods. When the canner is fitted with a pressure valve the same as the smaller cooker, it can be used only for canning specific high acid foods. A pressure gauge must be present with the valve on the canner, in order to use it for canning low acid foods, meats and fish. The pressure gauge must be monitored during the canning process and the heat adjusted in order to maintain the recommended pressure level for a specific period of time, to safely cook and can certain foods.
If you are looking for an implement to cook under pressure tough cuts of meat or just to shorten the cooking time, you should get a pressure cooker - either stove-top or electric.
Saving Time With a Pressure Cooker
5 Reasons to Cook With a Pressure Cooker
If your intent is to can and preserve your garden harvest or other foods, buy a pressure cooker/canner and ensure that it has a pressure gauge, not just a pressure valve if you want to safely process low acid foods, meats or fish.
If you like the idea of pressure cooking AND canning, you can have the best of both worlds by buying a pressure cooker/canner (with pressure gauge) and using it for canning, as well as to pressure cook your meals. However, as mentioned above, pressure canners are very large and heavy to handle, and bulky to store.
Though one piece of cookware sounds like a good idea, you might find it inconvenient to take out such as large implement for a 4 lb roast. Because I like to can and pressure cook, I have both models and that's something you may want to consider.
