I'm Fed Up with Electronic Measuring Gauges !
philf:
I too have had failures with Mitutoyo digital calipers. The latest to die was a 300mm. My first 150mm Mitutoyo cost me about £90 a long time ago. I took it in to work to test in our standards department. It was atrocious! Typically 0.06mm adrift from the grade 1 slip gauges. Mitutoyo replaced it but without an apology. I only use them for rough measurements when I may be working to >0.1mm.
Here are my trusted digital instruments and they don't need batteries:

But how do I measure the size of a Black Cat in a Coal Cellar with Solar Calipers :lol:

I have to say that the Mitutoyo 'digital vernier' that sits on my workshop desk most of the time never ceases to amaze me how close it is against gauge blocks, and the poor thing gets the occasional bit of rough handling by accident.

Hi Andrew -- I have a pair of "Harbor Freight Chinese electronic calipers from the late-1990's that still work reasonably well (i.e. +/-.001 inch) against my (1972) gauge block set. -- Lew

Somewhat against the thread ..
I have a big collection of Very Good import chinesium calipers and digitals mics, both for my own use and for limited resale.
I bought 5 different brands to test, as 1" digital mics, and found a really good brand I was happy with.
Change the batteries about 1 / year on about 8 of, that I use myself.
Digital 1 micron mics to 6", plus 2 sets of 100 and 150 and 200 mm digital calipers.
The digital mics are accurate to as good as japanese mitutoyos, about 1-2 microns, based on multiple blind tests with gage pins.
The calipers are about as good as the best Mitutoyos, or similar US federal or Mahr stuff.
About +/- 0.01 mm throughout the range.
I buy the 2032 batteries in sets of 20 and they last me a few years.
The digital mics are much faster and more accurate than the traditional mechanical ones, have 2 sets of.
Generally, the digital mics are about +/-1 unit or 1 micron off, at most, and almost always trending only in one direction.
Upwards, iirc.
