About Mitutoyo 531 Series Vernier Caliper, Stainless

The Mitutoyo 531 series vernier caliper has a spring-loaded thumb clamp to control the sliding movement of the vernier scale, and two sets of jaws and a depth bar for four-way measurement in inch and metric units of outer dimension (OD), inner dimension (ID), step, and depth, 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 an upper scale measuring in inches and a lower scale measuring in millimeters. A spring-loaded thumb clamp on the vernier scale locks the sliding jaw’s position, allowing scale movement only when depressed. A 14-degree vernier face angle improves visibility and helps prevent parallax error in measurement reading. The caliper’s two sets of jaws provide the capability to make OD and ID measurements, as well as step measurements, where the butt end of the fixed jaw measures one end of a work piece before its upper/lower or inner/outer "steps" are measured. A depth measuring blade with rounded edges provides the ability to make depth measurements. The scales are raised to slide easily and protect the graduation markings. A thumbwheel permits fast and easy measuring. A clamping screw on the upper scale rotates to control scale movement and locks to hold the sliding jaw’s position. The caliper is made of hardened, corrosion-resistant stainless steel with a satin chrome finish that helps reduce glare. The caliper meets Federal Accuracy Specifications GGG-C-111B. Calipers measure the distance between two opposing sides of an object. They make inside, outside, depth, or step measurements, according to their type. Calipers are commonly used in architecture, metalworking, mechanical engineering, and machining. The simplest calipers have two legs to mark the two points and require a ruler to take the measurement. More complex calipers use two sets of jaws instead of legs and have up to two
