950-241 Digital Dial Indicator, 0-12.7 mm Range, 0.001 mm Resolution, SPC Output, High-Accuracy Measurement Tool for Workshop, Laboratory, and Industrial Quality Control

The Mitutoyo 950-241 hermaphrodite caliper with a 4” range is used to scribe lines a set distance from any workpiece edge. The curved leg is run along a surface edge while the scriber marks at a preselected distance, designating a line parallel to the workpiece edge. This caliper is made of high carbon steel with a brushed, natural steel finish.

The 950-241 takes measurements in both inch and metric units. The inside depth is 6". The measuring range maximum is 4"/100 mm.

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, machining, manufacturing, carpentry, and medicine. 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 all 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 dial caliper is used for measuring size differential between two objects, as well. The digital caliper takes the same sort of differential measurements as the dial caliper by zeroing the display at any point along the slide, with an LCD (replacing the dial) that displays a single, easily read value in both English and metric units. Some digital calipers can hold data readings between measurements and send them to data collection devices.

Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
