I bought a pressure canner of Amazon, unfortunately the manual is entirely in Chinese.
It doesn't look like the two types of pressure canners I have learned about, which are "weighted gauge" and "dial gauge".
It has 3...things on the lid and I am not exactly sure how to operate it. Is this basically dial gauge pressure canner? What are the 3 things? Vents?
The product was fairly expensive and looks well build and judging by the temperature gauge it can reach very high pressures, so I assume, that it can be used for canning, but I am not sure how to find information on it.
It looks like this:

After scanning part of the manual with an OCR scanner and using google translate I learned the following: The middle valve is a safety valve. The right one is for manual release. The left one with the pins sticking out is an automatic release, possibly adjustable.
