Spurtar Vernier Caliper Measuring Tool 6", 0-6Inch/0-150mm Manual Non Digital Calipers, 0.001"/0.02mm High Precision Durable Micrometer

Love this tool. It sits on my desk and I use it almost daily, often several times a day when i do use it. it is accurate, battery free, solidly built, and looks good. Precise is the way I would describe this tool!

Nice tool. Vernier are not exactly in vogue, but this is very handy in most application. It reads well and moves well. Of course it is not a Starrett or Mitutoyo, but it isn't prices as those and other brands. Buy it for what it is and you will probably be happy with it.

Pros: (1) Mine lines up on 0 pretty well when fully closed. (2) The plastic case seems fairly protective. (3) The slide feels snug, not sloppy. ((4) It came with a decent, separate, 6 inch / 150 mm metal ruler.) ||| Cons: (1) The ad says "smooth slide with no grittiness" but the slider movement on the caliper I received definitely feels somewhat gritty. Lubrication helped a little bit. (2) The Inch scale does NOT look like the scale in the ad pictures. The whole-inch numbers on the caliper I received in June 2024 are unnecessarily small & hard to find. I improved the situation a lot by putting a red dot (with an Extra Fine Point Sharpie) above each whole inch number. (See my picture.) (3) If the printed markings are etched, they are not very deep, so the ink may wear off prematurely. (4) The "user manual" is a single 7x10 inch piece of paper with some helpful info, but their example for reading the metric vernier was poor (not helpful). Their online metric vernier example is much better than their printed one. ||| Notes about certain other reviewer complaints that I feel might be unjustified - (1) Some reviewers complained that this caliper can't be stainless steel because it is attracted to magnets "and stainless steel is not magnetic". However, there are over 50 "standard" formulas for stainless steel and some types (hardened martensitic stainless steel for example) are indeed attracted to magnets. (Unfortunately, the ad doesn't specify the type of stainless these are, it only says "hardened stainless steel".) These calipers may or may not resist rust well, but that ability cannot be judged strictly by how well they stick to magnets. (2) Some reviewers complained that the marks on the inch rule are at 0.025ths (40ths) of an inch instead of 1/2, 1/4, 1/8, etc. If you want fractions and you don't need to be more precise than 16ths, you should get a different caliper. However, many metal workers work to decimal inch specs, so this scale is right for them. Plus, getting a precise value from fractional inch vernier calipers involves nuisance frational math because you have to add x/y (from the bar) to z/128 (from the vernier) where y can be 2, 4, 8, or 16. Then you'll probably want to try to reduce the resulting fraction to have a smaller denominator (if you can). (For example, you might read 5/16 + 6/128. (That's 5/16 from the bar + 6/128 from the vernier.) Some math: 128/16=8, so multiply 5/16 by 8/8 to get 40/128. 40/128 + 6/128 = 46/128 = 23/64.) Decimals are MUCH easier to work with than fractions with different denominators are. (E.g. you might read 3 x 0.025 + 0.008 = 0.075 + 0.008 = 0.083.) If you must convert from a decimal inches caliper to fractions, using a chart is pretty easy (you just have the nuisance of keeping the chart close by).

I find great value in this tool. With proper care, it should last a lifetime. I do not know why Amazon desires that I mention Battery Life; but I will say this model was specifically selected because it requires no battery, has no electronic display or any digital functionality (to fail or go out of Calibration). Best described as, "Analog baby." Accuracy confirmed against a different, trusted, 0.001 Caliper and this thing is closer than the listed specifications give it credit for. If for some reason you cannot read a labeled slide-rule, this probably won't work for you. For everyone else, this is the simple, accurate, functional Caliper that you are looking for. I will leave it to a hand model to demonstrate that the thumbscrew locking operation is excellent and smooth, it has smooth and stiff slide-action (not sloppy at all), nice probe depth and allows grip and control in use. Case and even a cleaning cloth included.

I just wanted a tool I could keep in the end table drawer near my couch for the times I need a semi-accurate measurement. Previously, I have purchased an inexpensive digital unit, which was a huge disappointment. It was flimsy and inaccurate. The jaws were not straight and the finish was pretty bad. next, I bought a plastic one (not digital or dial), reasoning that a well-made plastic one would probably be as accurate as the cheap digital unit. The plastic one was laughably bad...the scale was off by at least 0.5mm and the play in it was way more than expected. I threw that one away after a day or two. Finally, I bought this one. I'm very pleased. It has acceptable error and is nicely made and finished. It's not a Starrett, but it works great for measuring this and that. Plus, it's cheap enough that i don't care if it gets misplaced or dropped. The plastic case is a nice plus.

I bought these knowing they are cheap low quality, but good enough to teach the basics of reading vernier calipers. I would not recommend for anything where precision really matters. Anything below .01 is really questionable. Parallel check of the outside jaws is off more than .005 due to improper adjustment of the moving jaw and slide. The fit and finish is what you’d expect for any inexpensive precision tool. However for a cheap set to teach basics and not worry about drops or calibration, these will work.

Ho recentemente acquistato un Calibro a Corsoio da 150mm / 6 Pollici in Acciaio Inox e sono rimasto molto colpito dalla qualità del prodotto, a partire dalla sua confezione. Il calibro è arrivato all’interno di una scatola di plastica rigida, che non solo assicura una protezione ottimale durante il trasporto, ma è anche perfetta per la conservazione dello strumento. La costruzione in acciaio inox del calibro conferisce una sensazione di solidità e durabilità. La precisione del micrometro di misurazione è eccezionale, consentendomi di effettuare misurazioni esterne, interne, della profondità e del passo con estrema accuratezza. Questa caratteristica è fondamentale per i miei progetti, dove la precisione è un requisito non negoziabile. L’uso del calibro è intuitivo e confortevole, con una risposta fluida e precisa nella regolazione. La scala è chiara e facilmente leggibile, un aspetto importante per garantire misurazioni rapide e senza errori. Il valore aggiunto di questo prodotto risiede anche nella sua versatilità. È adatto sia per professionisti che per hobbisti, rispondendo a una vasta gamma di esigenze di misurazione. Inoltre, la robustezza del calibro mi fa prevedere un’ottima longevità del prodotto, rendendolo un investimento valido nel lungo termine. In conclusione, il Calibro a Corsoio da 150mm in Acciaio Inox è uno strumento di misurazione eccellente, sia per la sua precisione che per la qualità costruttiva. La cura nella confezione e nella protezione dello strumento aggiunge ulteriore valore, rendendolo un acquisto altamente raccomandato per chiunque abbia bisogno di uno strumento di misurazione affidabile e durevole.

Very good product for the money. I was concerned that the accuracy would be off, but turns out it is super precise and I have been able to maker some very precise fittings using this tool. A good purchase.

Nadat ik mijn twijfels had gekregen over de nauwkeurigheid van de gemiddelde elektronische schuifmaat, weer een ouderwets model aangeschaft. Prima mee te werken, en goed af te lezen. Voelt solide aan, werkt altijd als ik hem nodig heb (geen lege batterij), en afleesbaar tot op 0,02 mm!! Onder de indruk!

Solide Ausführung des Messschiebers - Macht was es soll --> Messen :-)

Esta muy bien la calidad y el precio! Ideal para el uso diario
