📏 Mitutoyo 500 752 20 Digimatic Caliper IP67: Precise Measurements with Enhanced Waterproof Performance Review

As long as you don't drop a caliper (ANY caliper) I really like the accuracy and durability of these calipers. I used my first pair for years until it started reading slightly higher than ±0.001 and retired them to the household/garage. My second set is only slightly different (in a good way). The battery door no longer requires a screw. The caliper is impervious to liquids, there were no problems. And it is also auto power off, no power switch. Just gently push the caliper and it wakes up…

Interesting features. There is no on/off button. Move the slider and it will wake up. Turns off after 20 minutes of inactivity. Buttons are switches that can fail, so fewer of them should improve reliability. It also claims a battery life of 5 years. The Mitutoyo electronics draw very little power thanks to my old 4" Mitutoyo caliper, but this one is even better. Love it. All accuracy checks with my 40 year old USA made Craftsman micrometer are fully compliant with the zero gauges as expected…

I had about four sets of inexpensive digital calipers that more or less "worked". But batteries always die, and although they claim to read to the thousandth of an inch, the last digit is always 0 or 5, and the readings rarely agree. This is what the brand's engineers use, and it does what it's supposed to do all the time. The display is also very large and sharp, unlike some LCDs that can only be read if you're looking at it from the right angle. Accuracy is how long a battery lasts. Based on…
