Review on 📏 ACEMETER Electronic Millimeter Conversion Measurement: Accurate, Efficient, and Precise Results by Josh Endricko

As a regular user of digital calipers in my workshop, I needed a plastic kit for quick measurements, especially on objects that can sometimes be damaged by the metal jaws of my technical calipers. For less than $8, you can't go wrong, and they're accurate enough for quick and general measurements like measuring appliances or confirming drill bit sizes. I compared them to my professional Mitutoyo calipers and due to the lower resolution of the digital readings they were within the specified tolerance/accuracy. They also use regular LR44 batteries and are easy to swap out if needed. Compared to my Cen-Tech plastic calipers from a few years ago, these ACEMETER calipers are not as accurate. I noticed that the slider is not that tight and therefore shifts slightly when measuring. Also, there is a slight gap at the ends of the measuring jaws, which can skew your measurements slightly depending on where you place the object on the jaws. The internal measuring pins also overlap slightly when zeroing, but can be sanded down with a blade if necessary, or simply re-zeroed when measuring. For less than $8, I'd like to make some adjustments to the calipers to improve accuracy, but the caliper sag can still skew your measurements a bit. When I don't need ultra precision these are my goto calipers, but it's always good to have a few metal calipers on hand for more precise work.
