The Mitutoyo 530 series vernier caliper has two sets of jaws and a depth bar for four-way measurement in inch units of outside dimension (OD), inside 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 both the upper and lower scales measuring in inch units. 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.
