Digital Vernier Caliper, Preciva 150mm Electronic Micrometer Calipers, Measuring Tools Gauge with Mm/Inch Conversion High Precision

Got to be the best £20 odd quid I ever spent, what a great buy, very useful bit of kit, well made, highly accurate, easy to use, digital read out, comes with plastic case to protect it, battarys supplied, well worth the money,

I don’t usually leave reviews, but I’ve been using this caliper for a few projects now and it’s good enough that I felt it was worth saying something. I bought it because I wanted to be more accurate with my 3D printing work, but I didn’t want to spend serious money. A Mitutoyo digital caliper which is top of the pile is around £110–£120 in the UK. This cost a fraction of that, so expectations were sensible. First impression was good. It’s stainless steel, has a bit of weight to it, and doesn’t feel like a toy. The slide is smooth and the little thumb wheel is actually really useful for creeping up on a measurement instead of overshooting it. Once you lock it, it stays put. Accuracy-wise, it’s been spot on for what I need. I checked it against a couple of known sizes and kept getting the same readings back, usually within about 0.02 mm. I honestly wouldn’t gain much by spending ten times more. The screen is clear, zeroes properly, and doesn’t jump around while you’re measuring. Inside, outside and depth measurements all work as expected, even on small holes where cheap calipers can be a bit sketchy. Is it as silky smooth or as refined as a top-end Mitutoyo? No. But it also doesn’t cost Mitutoyo money. For normal workshop use it does exactly what it should without getting in the way. If you’re a hobbyist, DIYer, or just want a reliable digital caliper without paying professional prices, this is a really solid buy. I’d happily buy it again.

Decent ... bit flimsy but to be expected at this price point ... seems fairly accurate

It is nicely engineered and feels right in the hand. Slightly ‘left hand’ heavy but acceptably so. OUTSIDE MEASURING JAWS: On holding it up the light, I can see that the machining is perfect. The gap, when virtually closed is absolutely even. INSIDE MEASURING JAWS: This is always more difficult to check because you need to look through the gap at a slight angle. It does however appear that the gap is not perfectly even. It is less than a thousandth of an inch out, by my eye-ball, and perfectly acceptable for my needs. There is a very slight roughness to the measuring surface which probably accounts for this. The 'error' will soon be nullified by normal wear and tear, so it really is not of significance. STEP MEASURING SURFACES: The calliper stands on end absolutely square - so the step surfaces are precisely made. DEPTH MEASUREMENT: Absolutely flush with the jaws held closed - just as they should be. The slider is slightly wobbly in the body but that does not affect the accuracy. Better that way that stiff. IN USE: The jaws can be held in place firmly with the thumb on the bulge under the display. Ergonomically, it is just right. The fine adjustment wheel is indeed a proper working wheel and not just a dummy plonked on there to make it look good. The locking screw works easily without having to apply too much pressure. Full marks then to Preciva for the design and engineering. THE LCD DISPLAY: It’s big and clear but it does not work well in cold weather. Anyone expecting to regularly work in the cold would be better off with a Vernier calliper or a Dial calliper. The manual says 5°C to 40°C operating temperature and it was less than that when it was delivered so, fair enough, it didn’t work properly. Whether you turn it off manually of leave it to turn itself off, it turns itself on again as soon as you move the jaws - which makes the on/off switch almost redundant. If you are travelling with one of these it may be a good idea to lock it with the top screw to stop it turning itself on all the time and flattening the battery. Remember not to close it right up though or you risk straining something. CR2032 batteries are pretty cheap and they give you a spare battery as well as the one fitted when it arrives. With a bit of care, battery life should not be an issue. MY FIRST ONE WAS FAULTY: I noticed that when pressing the 'ZERO' button, the display always said '7.77' or ‘0.01’ instead of '0.00'. Measurements sometimes worked normally but in some lighting conditions it was all too easy to see the parts of the LCD that you should not be seeing - which makes reading it a bit worrying. Having realised that problem, I gradually opened up the jaws beyond my normal range and I noticed that there were a great number of random readings appearing. Far too many to be acceptable, so my first one had to go back. Fortunately, the replacement is a brilliant tool at a bargain price. ACCURACY: To test the Preciva, I measured three drill-bits (5.00 mm, 2.50 mm, 1.20 mm) with 5 different devices. I measured each shaft three times with each of the 5 instruments - i.e. 15 measurements of each object. The table below shows the average result in millimetres. (The table may not survive re-formatting by Amazon so read carefully). NOMINAL SIZE: 5.00 2.50 1.20 Vernier Micrometer: 4.957 2.508 1.200 These readings did not vary. Vernier calliper: 5.02 2.54 1.26 These readings did not vary. Plastic calliper: 4.70 2.30 1.10 Varied by 0.20 over three readings. Faulty Preciva calliper: 4.94 2.49 1.18 Varied by 0.10 over three readings. Second Preciva calliper: 4.96 2.50 1.19 Varied by 0.02 over three readings. The micrometer readings and the Vernier calliper readings were absolutely consistent. The Faulty Preciva and the £5 plastic digital calliper varied with each reading but the Replacement Preciva varied only very slightly… On the ‘5.0’ mm object it varied 0.02 mm On the ‘2.5’ mm object it varied 0.01 mm. On the ‘1.2’ mm object it varied 0.00 mm. The measurement ‘error’, if error it really is (probably is), is a maximum of 0.01 mm. All of those results are pretty damn good for a budget calliper! My Vernier micrometer reads '0.00' when closed right up, using the torque limiter. I would guess therefore that it is reliably accurate at these small measurements. On that assumption, the Preciva calliper is more accurate than the Vernier calliper(!) and it is of course much quicker to read than the Vernier calliper. Very rarely will I need anything more accurate than the Preciva and if I did, I would be using a micrometer anyway – so the Preciva is a bargain! CONCLUSION: It is a shame about the faulty LCD on the first Perciva but the replacement one is a gem. Highly recommended and well worth 5 stars at that price. The £5 plastic calliper result was interesting. It is the least accurate, as should be expected, but for most purposes, it is good enough. How often do you REALLY need to measure closer than 0.3 mm? PLEASE NOTE THAT THE PICTURES ARE OF THE FAULTY ONE. THE REPLACEMENT IS 'PERFECT'.

Je n’ai jamais rien compris au pied à coulisse, Manel, mais je me demande comment j’ai fait pour m’en passer. Rien à redire : de qualité, très précis, pour un prix modique. Pile de rechange, explication claire, bref, très satisfait.

Voorlopig doet deze wat hij moet doen. Lage prijs afwachten na meer gebruik

fungerar som den ska.

Un ottimo calibro alta visibilità e molto preciso

Ich bin mit dem digitalen Messschieber von Preciva absolut zufrieden! Die Verarbeitung aus hochwertigem Edelstahl fühlt sich sehr robust an und macht einen langlebigen Eindruck – ideal für meine Werkstatt und den Hobby-Einsatz. Das große LCD-Display ist super gut ablesbar und zeigt die Messwerte klar und ohne Schwierigkeiten an, egal ob Innen-, Außen- oder Tiefenmessungen. Die Umstellung zwischen mm und Zoll funktioniert problemlos und die Ergebnisse sind äußerst präzise. Die beiliegende Ersatzbatterie ist ein kleines, aber sehr hilfreiches Extra, sodass man gleich loslegen kann, ohne erst etwas besorgen zu müssen. Insgesamt ein tolles Werkzeug, das ich jedem Heimwerker oder Profi nur empfehlen kann!
