Choosing Electronic Caliper: Brands, Accuracy & Budget (PLN 80-120) - Luna Analog Alternative

Which electronic caliper should be chosen up to PLN 120 (PLN 80-120), which company do you recommend? I currently have an analogue "LUNA". It should be as accurate as possible.

In this price range, you won't find it very accurate, there will be a lot of slack and inaccurate reading, best regards.

You must remember that showing a caliper is one thing, and its measurement uncertainty is another. Now, most electronic calipers have a display that points to an accuracy of 0.01mm. However, do not be fooled, because there is no way that with such uncertainty - that's what it is called now, she is measuring. There is also the topic of calibrating such a tool, if the measurement is to be reliable, it must be systematically checked and calibrated. If you are unable to ensure regular checks, give it a go and buy a supermarket.

Well, unless a friend is satisfied with such accuracy, I think that the accuracy to 0.1 mm is already available in this type of calipers.

Well, yes, only a friend writes about the most accurate, so I try to enlighten him so that he does not blindly believe the indications.

It has to be pretty or accurate ?
If nice, then anything for PLN 30, and if accurate, for example, Mitutoyo or VIS (Polish production).

Not bad prices of these calipers: /, I guess I'll stick with the good old Polish "luna", thank you for making me aware , Come on, I don't deny that I am still tempted by the digital one but max PLN 120, thank you.

Then buy yourself a digital one, cheap but metal, not plastic. They are on Allegro for about PLN 30.
After using a digital one for a while and controlling it with an analog, you will get into practice.

I personally have two different ones.
For such daily measurements, I use one for PLN 30.
When I "go to the machines" I take the good old Polish VIS (made on the Mitutoyo module, anyway - it used to cost almost PLN 900).

I will add a little: I am playing (more and more seriously, I recently launched two factory winders) in reeling of tactics, I needed something that would measure the diameter of the winding wires up to about 2mm with an accuracy of 0.01mm, I got a micrometer from All for the Christmas tree (I suggested such a gift myself) for the price about PLN 25 (many sellers, prices different as well as packaging, visually it seems that the manufacturer in China is one), I took it for the first time with a certain amount of shyness ("intimidating" price ...), measuring tips secured, I washed with wax '' in gasoline, left for a few hours at room temperature, zeroed (the key is included in the set) and measured a few wires from known (described) spools, I borrowed gauge plates from a friend and also measured them with a micrometer, I am amazed at the accuracy of the measurement results (I use for about a year) and good quality of the device at an amazingly low price. When the temperature drops from 22 to 16 degrees (the heating of the basement is reduced, where I move the hit with a jump), after a few hours, the zero setting should be corrected by about half a plot.

The author is looking for a caliper, not a micrometer - so what does your post bring?

The caliper will be used once in a while, maybe it's my convenience, but I don't want to look for the exact scale on the scale and the digital result is ready

But digital can also be bought for a dozen / several dozen PLN. For such applications, it makes no sense to buy MITUTOYO, TESSA or VIS.

I was looking for and found something like this: ELECTRONIC caliper 150mm Corona C3431 0.01mm:
Characteristic

length 150 mm
accuracy 0.01 mm
LCD display
measurement in mm and inches
has the CE mark
I think that for my hobby applications it will be ok
made of steel
plastic case

As long as it's not plastic ("made of steel"), that's enough for you.

yes it is made of steel and what else it looks pretty nice

He can go ahead and take, although I would look for a cheaper one. But cool.

You can always order from china to aliexpress.com

Cheaper than what? You don't know what the author found.

But what do you mean? After all, the author has clearly identified the model he is going to buy.

I do not believe that this caliper measures with an accuracy of 0.01 mm.

This is the accuracy of the display. It is by no means a measurement uncertainty. We did statistical tests of calipers with such an indication and after many attempts it turned out that the tolerance of dimensions measured with such a caliper should not be higher than 0.4mm. Of course, one cannot suggest it, the tests were carried out by different controllers (different clamping force), in different conditions and the parts to be measured were made of different materials.
Generally, no caliper measures with a measurement uncertainty of 0.01mm.

Not true - Mitutoyo ABsolute Digimatic series.

I think my colleague did not read something. The caliper he writes about has a display with a resolution of 0.01 mm, so this alone disqualifies it from measurements with the same uncertainty.
Besides, the measurement uncertainty was mistaken for repeatability (please refer to the reading).
I enclose the specification from the manufacturer's website:

Technical Data

Accuracy: Refer to the list of specifications
Resolution: 0.01mm or .0005 "/0.01mm
Repeatability: 0.01mm / .0005 "
Display: LCD
Length standard: ABSOLUTE electrostatic capacitance type
linear encoder
Max. response speed: Unlimited
Battery: SR44 (1 pc.), 938882
Battery life: Approx. 3.5 years under normal use

The table below this specification clearly states:
Accuracy - +/- 0.02mm - which gives us 0.04mm

A colleague will learn to read and understand what I have written.

This is not true and I wrote that too.

Let a friend read what he writes sometimes, but with understanding.

Probably not really.

After all, is it true or not?

You too.

I end this discussion. I invite you to a short lecture on metrology during your stay in the area. My knowledge is supported by many years of experience in industrial metrology, documented with many certificates (including GUM), so I will be happy to share it.

Two hundred doughs is none. I had such for a hundred (with Hart), I had such for two hundred, I don't remember the company. Either the battery lasted a month, or the guard on the guide rubbed off. When they opened them quickly, I had stupid things on the display.
I bought from Mitutoyo, it really measures, but I don't like it anyway. I prefer the regular one with the vernier.

And here my colleague touched the heart of the matter.
We bought a few "lidl" calipers for "fast" measurements without any pressure on accuracy (use from time to time).
We borrowed GUM-certified sample blocks from our neighbors.
Surprisingly, practically all of these Chinese devices measured much more accurately than you might expect (we measured up to 1 cm thick).
Unfortunately, my calipers had problems with zeroing, and the others have what my colleague described above.
After some time, the scales began to peel off.
What's more interesting in our "model" Sylvac, after 5 years of use, the scale also begins to peel off.
Having learned from this experience, I decided to buy Mitutoyo when I bought it for a house - I hunted for a "new" for a long time at a reasonable price, but I managed to hunt for about 250 zlotys.
Be careful because the 500 196 20 series is massively counterfeited by the Chinese and you can get into the bottle by buying from an unreliable source.
To sum up - cheap calipers for occasional use (if you get a good copy) are approx.
Having a guarantee, you can always return (as in my case), but you have to keep the receipt.
