Cheap digital spirit level accuracy

As they contain no spirit, surely the are digital inclinometers?😉

Do digital vernier calipers have a vernier scale? 😉

There are digital precision levels used for setting machinery dead level etc, not for measuring angles like these digital inclinometers.

Hi, maybe they should be called a spirit and digital level.

As I said previously, a lot of precision electronic levels still use a bubble. It’s sensed electronically, corrected and displayed.

Hi, well I Goggled them digital spirit level. and the answer I got was that the bubble isn’t measured, so is Goggle wrong?

Many combine traditional bubble vials with digital functions. I’m only interested though in setting relative angles. Today I’ve been squinting through a loupe to set my vernier protractor (or perhaps more correctly a bevel – Moore and Wright 994). I doubt it’s any less accurate than a Chinese digital unit, and in many ways less useful when setting up work for milling angles.

It’s wrong. Certainly for the AI summary to state that they only use MEMs is nonsense. Yes MEMs are used in some modern ones but it’s “smoke and mirrors” on accuracy. Typically to get haigh accuracy each one has to be corrected in software.

Bubbles and pendulums are still used. See:

Well done, Robert … you have outwitted the AI

ChatGPT, in common with Google, denies the existence actual physical bubbles in these devices … and then provides a link to this !

Hi Robert, OK, but I don’t think they are in the same cheap category as Mick Bailey was asking about.

Regards Nick.
