cheap digital vernier calipers.

odd one this.

my 7 yr old girl as put measurer like daddies on xmas list.

finally sussed she means my digital vernier caliper, i have rough use set i let her use but she wants her own.

where can i get her cheap set?

not got e-bay account.

ta

I often see them in Lidl for about £10.oo

Question: Do you mean digital or vernier? They are not the same!

called as per arc do in their catalogue.

that's how i figured what she wanted as left it open on that page.

buts it's digital

called as per arc do in their catalogue.

How amazingly easy it is to corrupt the english language! Next we will have curved straight edges?

I presume arc do not offer, for sale, a vernier caliper? So possible misrepresentation to catch the attention of those that really wanted a vernier scale?

But, I suppose, my analogue clocks still have digits painted, or printed, on the clock dial..... but they are still analogue.

See my test in the latest MEW.

These ones from Machine DRO cost less than £13 and are better finished and performed better than typical budegt calipers.

I honestly wouldn't bother buying the discounter's ones again having seen these.

These are worth looking at too:

These are half price at just over £40, they seem to have sold out of the 6" version, which I found to be a really nice piece of kit.

<edit!> Just seen these are for her! The bargain ones above are a good choice as they don't have the sharp edges many of the supermarket ones have.

She sounds sensible but PLEASE know that small batteries can cause terrible injuries if swallowed.

... Despite the use of 'digital vernier' by [even] our illustrious Editor in his recent test.

I got this **LINK** for £6.99 to go in my apron chest pocket - it is 75mm so it fits perfectly, and is plastic so it won't kill me when I fall on it (similarly maybe better for a 7 year old)

I know you said no ebay, so I think this is the same:**LINK**

I would also recommend to the grown ups - it is obviously not super accurate, but is great for checking stock size etc, and as it fits in the pocket is always with me. 2 caveats - it zeros when switched on, so you have to remember to do so with it closed, and no depth measuring pokey thing

How about one of these. No batteries!

Neil's warning is about batteries is deadly serious - have a look at this report. There's no way I would give a child anything with a button cell in it.

Every cloud has a silver lining. Next time I need to bump someone off I shall feed them a CR2032.

Probably not important for a kid but the eBay/Amazon one has an ambiguous listing:

will provide precision readings from 0.1mm and 0.01in.

Specifications:

Resolution: 0.01mm (0.0005in).
Accuracy: ± 0.2mm (0.001in).

I once got caught out buying a cheap plastic pair for 'hack' and they only read to 0.1mm. OK for checking stock sizes or making a drill depth readout.

You could glue the battery compartment shut. Kids toys always (should) have a screw on the fixing tab.

I recently bought 3 (dont ask why) cheap £7-8 calipers off ebay from china. One is workable, one is difficult and I got my money back on the third as it was utterly useless. I wanted a mitutoyo but theyre just that bit too dear so I splashed out twenty notes an a sealy and it is very nice(moral here is dont get a ultra cheap one from china). I read about the button battery issues a few weeks back, there are calls to ban them from kiddie products and its not hard to see why.

Google "Plastic calipers", Amazon do them for 1.78. I have a promotional pair which are good enough for woodworking.

I would ask the young lady why she wants the calipers. It may be from scientific interest, it may be because the matt chrome finish looks cool. This is from my own experience.

How amazingly easy it is to corrupt the english language! Next we will have curved straight edges

A straight edge is a curve of infinite radius

Absolutely, but in crass advertising gimmicks, that might not be a good move. Same as a circle being a polygon. Very few know that to define a square needs four equal sides and only one right angle.

Very few recognise, or even know, that a battery must comprise of more than one unit; inarticulate beekeepers refer to different size hive boxes with incorrect nomenclature - calling one size a 'super' but it likely being used as a 'brood' box, orceven vice versa

There are lots of other scenarios where units are mixed, etc. Just not good enough for precision in any particular discussion. Accuracy and precision are another pair of misused words.

Dumb journalists who don't know the difference between MW and MWh, convert approximate measurements in metres to an exact conversion to the nearest inch (or even foot) in Imperial, etc, etc.

All this makes no odds. There is no such thing as a digital vernier. Using someone else's mistake to claim an incorrect answer in an exam is right, will not cut much ice with the examiner!

Whilst we're at it ... let's do Monsieur Vernier the courtesy of capitalising his name.

P.S. ... We have been down this 'no such thing as' path before; and I suggested that it may actually be feasible to construct a 'digital Vernier' in the true sense. If you consider the method of reading a Vernier scale, the process [including the human operator] is 'digitised' by judging the nearest alignment of lines; and that could be replicated electronically. [N.B. nothing in this is intended to condone the use of 'digital vernier' to describe a caliper/calliper with digital scales and a numeric display]

let's do Monsieur Vernier the courtesy of capitalising his name.

Let's also know that there are ttwo types of noun - proper and common.. Nor do adjectives require capitalisation.

I merely suggested a courtesy.

MichaelG.

Never knew vernier was an adjective, or am I misunderstanding, again. We should stick with the the common journalistics - Double decker bus, twice the size of Wales etc. etc..
