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

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 based on the supplied calibration certificate. so pitch and depth readings checked with micrometer sensors too Ring sensor should come tomorrow so ID jaws can be checked but they match readings on my old Mitutoyo so don't expect any problems Very smooth slider action u no signs of zero deflection or preload.
