Large LCD Digital Caliper

Really pleased with this purchase. I find it invaluable for my hobby which requires precise measurements of diameters of turned metal bars. Product feels top quality, extremely accurate, automatically turns itself off after inactivity to save battery life. The carry case is a nice touch too, and all for a reasonable price.

Great measure, clear and precise.

Well, on opening the cardboard sleeve and it’s blue plastic vacuum formed box you get to see it looking beautiful and shiny. There’s a couple of spare batteries, instruction manual, calliper tool and even a little screwdriver to be able to change the batteries with. The unit actually came with batteries in it which is great and providing a spare set is even better. I went for the slightly more expensive metal version as apposed to the cheaper plastic jawed one because I like to buy things that will hopefully last longer. Instruction manual is good, although it is pretty easy to understand, you can change the measuring unit via a little button, lock the device via a little top screw and it’s easy to operate the device for external, internal, depth measurements. Display was clear and easy to read and comes with off button to save its batteries. Instruction manual had a couple of mistakes in it, mentioned the locking screw was number 3 on the diagram and it’s actually number 2, (3 is the lcd display) and then also says to reset the unit by taking out the battery and it resets after 30 “secretary” which I presume should be “seconds” So it lost a star because of those mistakes, it’s the details that count. Unit feels well made, no issues with working it and hopefully it will serve us well for years to come.

I wanted a simple caliper to help with my 3D print modelling to get accurate sizes for items I wanted to create. This is working perfectly for my requirements. I had seen so many that were just flimsy and felt like they would break easily, this doesn't feel like that. I feels quite sturdy. The display makes reading the size of items you are measuring really easy, especially if you have poor eyesight as the display is large enough to read. It also has the measurements on the tool itself if you prefer to use that or if the battery for the display has failed. It comes with a spare battery for the display, so this just increases the value for money. It also comes in a plastic case that can be used to protect the caliper from damage while you are not using it. On use you should just check to make sure that the starting value is 0. If it isn't reading 0 when it is fully closed then there is a button on the display to reset the 0 point. There is a second button on the caliper to switch between inches or millimeters.

I was planning on returning these as the readout was wrong and showing half measurements (ie. at 50mm the display shown 25mm) and the mm/in button to switch between measurements wasn’t working. But after removing the battery and leaving it out for 30seconds and reinserting, it reset the device and all works well. For the price they’re really good. The ‘carbon fibre’ one (pretty sure it’s plastic) feels a bit delicate but the accuracy and ease of use are great after the battery reset.

I wanted a replacement for my old vernier calipers as I'm getting old and its difficult to see the scale so I thought I would give these digital ones a try. So pleased I did as not only are they very accurate, the display is very easy to read. To check the accuratey I got my trusty feeler gauge out and, after checking some of the gauges with both my old vernier calipers as well as my micrometer to verify the sizes were correct I gave these new ones a try. And they were bang on.. well within their stated tolerances. See my video showing the 0.28mm gauge. It was difficult to film one handed but you can see this new digital vernier caliper measured it correctly. (I did test more but did not film and it was accurate on all of them) They are very well made and feel substantial in the hand. Come if a protective plastic case with a couple of spare batteries. Even has a conversion scale on thr back of them. All in all.. a very precise tool for relatively little money. Very happy with them.

If you're looking to get an accurate reading of "Is it closer to 1.5mm or 2mm" then these are fine. If you need even the advertised precision of 0.2mm+- then I would look elsewhere, these are always -0.1 to -0.3 when I put them back to 0 so they are not keeping their zero correctly. For £10? Sure whatever, if I stood on them and broke them I would even be mad.

Looks great and at the start it worked, then several months down the line when I went to use it again and no display! I did what was suggested - take battery out, replace after 30 seconds - No Joy. Put a new battery in - no joy. The Caliper has been kept in its case with the silica gel bag it came with. Now its too late (to send it back??)
