Digital Fraction Caliper gives you highly accurate readings of inside, outside, step and depth measurements, with a digital display that much easier to read. Digital Caliper is great for two purposes: one, getting incredibly accurate measurements (to 0.0005", 1/64th" or 0.01mm); and two, doing everyday measuring without going blind counting hash marks. Just zero the reading, set the caliper ends where needed and read the digital display. Easy-read caliper switches between inches, millimeters and fractions and delivers accurate readings of inside, outside, step and depth measurements. Your tired eyes deserve a break!
