Can you pressure can in the Presto Precise Digital Pressure Canner?

Last reviewed July 2026.

Only the manufacturer says so. Presto's claim is quoted verbatim above, and its basis is Presto's own thermal validation — the company describes testing 'utilizing multiple thermocouples to assess temperatures at many different locations inside the unit', including inside jars. That is a real engineering effort and it is also a manufacturer's internal claim, not an independent authority's recommendation: NCHFP's electric-appliance guidance stands, and Utah State Extension's position is that 'electric programmable pressure cookers of any brand are inconsistent at higher altitudes and should NOT be used for low-acid canning'. If USDA or NCHFP ever endorses a specific electric canner, this verdict changes — the authority wins.

How to read this

The line that matters in home canning equipment is who stands behind the claim. USDA process schedules were developed on stovetop pressure canners — NCHFP describes the equipment class and has stated plainly that those processes were not developed for electric multi-cookers. A manufacturer's own thermal validation can be genuine engineering and still not be an authority's recommendation — see what "meets USDA guidelines" does and doesn't mean. And a boiling-water canner is the right tool for high-acid foods and the wrong one for everything else.

What does have a USDA-process basis

This is the part worth being blunt about: no electric pressure canner currently has a USDA-process basis. Not one — it is not that this particular model missed out. The published processes were written and tested on stovetop canners, so if you want to pressure can low-acid food against a tested process, that is the equipment class you need.

These are the canners the published USDA processes were actually written and tested for. That is not our opinion about build quality — it is whether a tested process exists for the thing you are holding.

Prices are indicative and drift; the verdict does not. Capacity and gauge come from the manufacturer's own specification.

Canning Score indexes what NCHFP, USDA and university extension programs have on record about canning equipment, with attribution — we publish no process times and no safety advice. Verdicts describe the state of the authority record for an appliance class, not a guarantee about any jar. For tested recipes and process schedules, use NCHFP (nchfp.uga.edu), the USDA Complete Guide, or your state extension office — or the Seal canning guides, which work food-by-food from the same sources. If an authority publishes new guidance, the page changes — the authority always wins.
