The Mitutoyo 160 series vernier caliper has a single set of nib-style jaws with rounded measuring faces for measurement in inch units of inner dimension (ID) and outer dimension (OD), and a fine-adjustment carriage for applications where the highest accuracy is required, especially in scientific research and in industries where parts must fit exactly.

The caliper has a dual vernier scale, with both the upper and lower scales measuring in inch units. It has two-way measurement capability: outer dimension (OD) and inner dimension (ID), with rounded jaw measuring faces for accurate ID measurements. The scales are raised to slide easily and protect the graduation markings. A clamping screw on the upper scale rotates to control scale movement and locks to hold the sliding jaw’s position. A fine adjustment carriage feeds the slider to allow precise movement of the vernier scale. The caliper is made of hardened, corrosion-resistant steel with a satin chrome finish that helps reduce glare. The caliper meets Federal Accuracy Specifications GGG-C-111B.
