I need 2 small digital protractors or "angle finders" that I can mount to 2 different machines so I can monitor and compare their angle while in use. Here's the kicker, I would like them to have a memory function to record the maximum angle because they will be difficult to read while the machines are in use. Is there such a thing?

Thanks,
Roland

I know of none that I trust. I have a high dollar one that I never use for that reason.

This Mitutoyo has RS232 output... Could that work?

Hmmm, maybe. But I might try this cheaper one first which I found on the same page. It has a hold function which may work.WESTWARD Magnetic Digital Protractor, Rectangular Head, —, 0deg to 360deg, 90 x 4, 2.165" Length - 2YNK6'|'2YNK6 - Grainger

Thank you

You can get similar angle boxes from from chinese sources for $10-20. I definitely would not pay grainger's price. All of them seem to have a hold function.

I have been curious about these two axis ones specifically but have never been willing to gamble on one: TLL 90S Super High Precision laser level LCD Display

I'd pay the difference rather than pay Grainger's price for a plastic box with a couple magnets though.

No recommendation, but I've seen bluetooth angle sensors that can be read on a cell phone, would that work? Perhaps the reader app would be able to capture the max reading.

These are not bad.

Rather slow response times but they do have a hold button and somewhat real time output to outside connections
Today's phones can do tilt for playing games or guiding your drone, I wonder how good they are at real world measuring?
The above nice but 0.2 degrees is a big window.

I have an AngleCube. I use it for ballpark stuff but I sure wouldn't trust it to do anything requiring much accuracy. Repeatability isn't great. I normally give mine a couple taps to settle it and that helps but still...
