Cheapo digital calipers here, good enough for bike stuff. £3.12 delivered.
Just received these. They don't exactly give off the impression of a precision instrument, which is disappointing for something that cost £3.12 to be send from Thailand. Everything is made of plastic.
They measure a 30.9mm seatpost I had to have as anywhere between 30.6 and 30.8mm. Should be good enough to tell the difference between parts, rather than accurately measuring the sizes of things.
You'll have to pony-up for Mitutoyo if you want Tstr Approved calipers, but these received a Cursory Nod for using the commonly available CR2032, rather than the LR44 usually found in <£10 precision instruments.
those -appear- to be the same as the callipers i got at Aldi a while ago (not sure if the internals are the same though). For £8 they've been pretty useful and, as far as i can tell, accurate.
