The non digital heaters are calibrated with spring tension or something (don't quote me) and often they aren't done well so you have to use some trial and error. I've had heaters which I set to their version of 25 and it's 30. Some where you set to 25 and it's 23 or something.
Thermometers can be dodgy too. I've found the floating glass ones to always be a bit off. Fluval sticker ones are hard to read. The marina ones I always use now because they are at the very least consistent with eachother, and consistent with a few of my heaters. I stick them on the outside of my buckets to water change to correct temp. If it is one temp on one bucket and I pour it into another bucket it is the same temp reading. So I have them on virtually every tank and (will) have on every bucket.
