Sadly the modern Digital calipers are not made to last not in the way the old verniers were.
We have four sets of 150mm Digital caliper here. Three are Mitutoyo and one is BATY.
In the Mitutoyo one one set I bought through the firm in 1986 for my hand loading to save me converting from metric all the time as before I was using my 200mm Mitutoyo Dial calipers. I got a set for dad as he was finding the dial ones which I bought him back in 1980 hard to read.
Later when I was sub contracting I bought a pair to use at work then as Cromwell Tools had the BATY ones on offer a pair were bought as back up for work.
One place I subbed at the service life of company provided digital calipers was about 8 months and they were worn out. The place ran 24hrs and each machine had it's issued caliper. It seems that the use of the micrometer is becoming a lost art.
Makes like Tesa and VIS should you come across them should also be considered.
I believe it was Mitutoyo that developed the digital caliper in about 1980. The 150mm version was the only one offered and they cost £400 a set back then. They bought the inspectors them where I was working at the time.
Mine only see occasional use now and dads are never used at all now however I keep one pair by my desk here JIC
