iGaging Digital Electronic THICKNESS GAGE 0-1"/25mm MICROMETER CALIPER Inch/mm/Fractions

Can't believe I waited so long before buying something like this. I regularly work with a laser cutter and had clumsily measured material thickness with calipers. This instrument measures thickness so much faster. It allows me to reach in away from the very edge which is particularly useful when checking rubber thickness which can vary. It is nice to be able to slide pieces of material from a stack out slightly and measure with great accuracy without having to pull them out completely just to measure their thickness. This instrument feels like quality metal (not cheap plastic) in your hand, but at the same time feels like it would not handle being dropped even a short distance. While measuring, you do have wiggle it around a bit to orient it to get the correct (lowest) reading. When you position the opposing finger bumps for best measurement, the angle of the material is not aligned with the case or arms or anything else I can see. That aside, it is quite easy and fast to get a reading within +/- 0.1mm (.004") once you get the angle stuff figured out. If you take more time, repeatable readings down to +/- 0.01mm (10um, .0005") are possible. The hardened finger bumps are replaceable - I don't know where to get replacements. They are also polished very smooth so it is possible to slide along a piece e.g. of rubber to locate thick and thin regions. I'm guessing you wouldn't want slide the finger bumps along the surface of clear or shiny material because the finger bump's hardness could mar the surface.

This instrument does what it's supposed to and provides a speedy and accurate means of measuring thickness. It was well worth the cost. My only gripe is it's not easy to hold when making repetitive measurements to help with this I placed a cell phone collapsible holder to the back plate making it a lot easier to hold and to zero.

iGaging stuff is fantastic for rookie or part time requirements. This is my second product from them. Truly a great product for the value. No its not a top end machinist grade Mitutoyo and as I don't own anything like that to compare this to its tough to say Not sure on how accurate or repeatable it is, but I have been impressed in the past and seem to be doing quite well with it so far for my needs just measuring the thickness of materials at different points.

I needed a gauge to verify wood thickness in my CNC shop. Regular calipers sorta work, but I need something that measures thickness away from the material edges. This started out OK, but then it began having trouble holding zero. Replaced the battery several times, but that didn't help. If I leave it on for a couple minutes and then work the jaws opened/closed, it settles down to the point it's somewhat usable. A real PITA when I'm trying to plane down wood to a very specific dimension. And the ON/ZERO button is iffy. Of course I didn't find all this out until the return window slammed shut. I put up with it until I could find something else. Hello brake rotor calipers, goodbye junk.

Unreliable/inconsistent fine measurement. Not recommended for thousandths of an inch. I needed something for measuring sheet metal to +/-0.0005" and this is not it. Probably ok if you work with wood and only need +/-1/32". It does read off in fractional inch, if you need that, as well as decimal inch and metric.

The gauge works ad advertised, and measures thickness well. My primary use is to measure boards in multiple places after planning. These work better than calipers for me, permitting me to measure on a small portion of the board, and not responding to slight tilt, as a caliper head does. Mine has a maximum measurement of 1.047", not the Amazon-stated 1.062". The tips are balls, approximately 0.1"D.

Make sure you remove the battery if you don't use it often, it drains while sitting inactive

This appears to be accurate enough for my cabinet shop. My issue is it is difficult to use. I am right-handed. I find no other way to hold and operate this unit other than using my thumb on the lower, straight arm and depressing the curved, upper arm with my forefinger. A little awkward at best, and fatiguing after using a few dozen (or more) times in an afternoon. I believe some sort of handle or handles on the side opposite the measuring arms would make this much better. Another annoyance was the installed battery was dead, fortunately, a spare was included in the package.

I have a point micrometer but micrometers have a small frame. This thickness gauge has longer arms so I can measure the thickness where I cannot use the micrometer. Like the point micrometer, you need to wobble this thickness gauge slightly to get the smallest thickness.
