These economical Vernier calipers can be used to make measurement in metric or English units. With two sets of “jaws” allow users to measure the inner and outer dimensions of objects. The caliper stem is for measuring the depth of objects. Caliper uses include measuring irregular objects and measuring round objects such as cylinders. The fine precision offered by these calipers are ideal for comparing minor differences in measurements, such as the affect of temperature on a metal.
