Is anybody on this august body able to recommend a digital caliper. The one I have is losing parts of its numbers so a second one would be good.
The version I have seems to be available variously between £9 and £25, at least working from the pictures, but I would be prepared to spend a little more on quality

Re: Recommend a digital caliper
Personally I prefer not to use digital calipers in order to avoid the hassle of flat batteries at inconvenient times ( the batteries these take are not always easily obtained in shops ) but to use dial calipers such as this: http://www.machine-dro.co.uk/150mm-metric-dial-caliper-moore-and-wright-141-series-.html I find vernier calipers to be awkward to read.

Re: Recommend a digital caliper
I supposed you tried replacing the battery?

Have you checked the battery is delivering the specified voltage...

Apparently the cheap digital callipers are on all the time -- only the display is switched off, and the power consumption is not significantly reduced. Better quality (= expensive) ones switch off properly. Also cheaper (LR44) batteries will last much less time than the more expensive SR44 type. There is an interesting article at

about this, but you still need to do your own calculations.

In a word, "Mitutoyo".
I have a set, they cost £*lots*, the battery is always fine in them - I have replaced it once in many years.
I have a cheapy set which I am willing to drop on concrete, etc.. the battery on them will fail very quickly. I also doubt its accuracy.
I also have mechanical ones, which don't require batteries, always work, but can be harder to read.

The same applies to any electronic device with a "soft" switch. I simply leave the battery cover off my cheap digital calipers and flip out the battery when I've stopped using it.

Re: Recommend a digital caliper
Following discussion about battery life in digital verniers I came across an interesting situation last week. I have three sets of digital verniers (and an 'old fashioned' one for when all the batteries are flat). They are all the same type ie. Aldi or Lidl. Until now a flat battery was obvious, they didn't work; this time something different happened. All measurements up to around 10cm were perfectly OK, beyond this the reading went haywire. It was only because I knew something was wrong that I checked against the printed scale on the slide. A new battery sorted it but I am now training myself to check against the scale on the slide to verify I have a 'ball park' reading before looking at the readout.

Dirt will make digital messurements go berzerk in addision to a flatish battery. Best give it a clean too boot.
I've a pair of a Halfords Advanced Digital Caliper's. £19.99 and a Lifetime Guarantee. Fantastic value!

Re: Recommend a digital caliper
Having grown up in an era where digital calipers and micrometers did not exist, I use manual ones. The skill of reading manual calipers is not that difficult to learn, and onece learnt stays with you for life. No battery to go flat, no display to fail and the only errors are those you make yourself.

I would agree that Mitutoyo are very nice. Had mine for 20 years, and the case is large enough to store the old battery packaging so that when it fails in 5 years you know which one to buy....
