Mitutoyo 532-121 Brand Vernier Caliper with Fine adjustment 300mm / 12 inch Model 532-121 Brand Vernier Caliper Vernier Caliper  (300 mm)

The mitutoyo 532 series vernier caliper has a fine adjustment carriage to precisely control 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. 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 graduated scales. Vernier, dial, and digital calipers give direct and accurate readings and are functionally identical, having a calibrated scale with a fixed jaw, and another jaw with a movable pointer that slides along the scale. The vernier caliper has a scale sliding parallel to the main scale for an additional, fractional reading to improve measurement precision. The dial caliper has a circular dial with a pointer on a toothed gear rack replacing the second vernier scale. As with the vernier, this second measurement is added to the reading from the main scale to obtain the result. The digital caliper takes a differential by zeroing the display at any point along the slide, with an lcd that displays a single value in English and/or metric units.
