I have a 150mm Dasqua “Mechanist Grade Dial Caliper” (sic), with a mechanical dial instead of a vernier, and 0.02mm graduations on the dial.
I got fed up with batteries going flat, and this mechanical calliper seems OK for the price and is very useful for my 3D printing work. It seems to be mass produced – the end stop and depth strip retainer are not quite square, (but doesn’t matter), and I cannot comment on its fine accuracy for metalwork or its repeatability.
But for the money, I think it is decent enough. It might well be ‘Chinese’ in origin – hence the slightly odd translations. But useful as a jobbing calliper for medium precision measurements, that if dropped or stood on, would not make you cry !
I also bought a set of marking and measuring gauges from Dasqua, and they are pretty decent for the price – again almost certainly Chinese but all laser engraved and CNC ground.
PS, someone mentioned RS. I have used RS for many many years for electronics, but be warned they seem to have really hiked-up their prices in recent years and seem to be going for big corporate budgets. Farnell might be a better bet these days.
