Makes length/diameter measurements three ways- outside, inside, and depth. Six-inch and eight-inch models display digitally 0 to 6-inches/150 mm or 0 to 8-inches/200 mm. At the touch of a button it switches from inches to millimeters with a resolution of 0.0005 inch or 0.01 mm. Accuracy is ±0.001 inch or ±0.03 mm. Easy-to-read digital display is 0.3 inches high. Zero button instantly sets unit to zero when jaws are closed or any reference point. Floating Zero may also be set in mid-measurement to read "difference results" without calculations. Precision Caliper is ideal for measuring the outside diameter of stoppers, the inside diameter of tubing, and the depth of holes. No lubrication is ever required on the ultra-smooth slide steel bar. Runs on the supplied battery for 10,000 hours.
