#Mitutoyo dial caliper series

Has the most moving parts most prone to drop damage.Some parts are plastic and more prone to scratches.Button to switch between imperial (inches) or metric (mm).Large display is fast to read, even at a distance.Here’s a list of pluses and minuses for each type. Still, some people prefer a fully mechanical tool.Įspecially if you’ve learned to read a certain type of tool – you may want to stick with what works. They’re a great choice for machinists, for woodworking, for reloading ammunition, or any other use where fast, accurate measurements are needed. This goes double if you haven’t already learned to read a dial or vernier tool.ĭigital measuring tools are very accurate, quick to read, and durable.

There’s been some debate over which type of measuring tool is better. Let’s jump in and find the best tool for your job. Starrett and Mitutoyo (pronounced “stare-et” and “mitt-oo-toy-oh”) have come highly recommended for decades. 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.What good is a measuring instrument if it’s not accurate and reliable? As with the vernier, this second measurement is added to the reading from the main scale to obtain the result. The dial caliper has a circular dial with a pointer on a toothed gear rack replacing the second vernier scale. The vernier caliper has a scale sliding parallel to the main scale for an additional, fractional reading to improve measurement precision. 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. More complex calipers use two sets of jaws instead of legs and have up to two graduated scales. The simplest calipers have two legs to mark the two points and require a ruler to take the measurement. Calipers are commonly used in architecture, metalworking, mechanical engineering, and machining. They make inside, outside, depth, or step measurements, according to their type.

Two sets of jaws provide four-way measurement capability: outside dimension (OD), inside dimension (ID), depth, and step, 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.Ĭalipers measure the distance between two opposing sides of an object. The caliper is made of hardened stainless steel construction with titanium nitride (TiN) coating on the beam wear surface helps extend caliper life. A clamping screw controls scale movement and a dial calibration lock holds the sliding jaw’s position. A thumbwheel permits fast operation with one hand. The smooth-moving dial is graduated to 0.001” and offers gear train shock protection. The dial uses a rack-and-pinion mechanism and is mounted on a gear track where each tooth equals one quarter of the dial revolution, and four teeth equal 0.1”. Its standard of precise measurement complements the use of the vernier caliper the dial provides an ease in reading and interpolating measurements which most vernier calipers, due to their need for direct observation of both scales, may not provide. The dial caliper is easier to read than the vernier caliper, thus safeguarding against user reading errors.

The dial can be rotated beneath the pointer to measure size differential between two objects. The main scale and dial are marked in inches. The second measurement is added to the main scale reading to obtain a final result accurate to the smallest graduation marked on the dial. As the dial moves over the main scale rule, the pointer rotates once to give the additional fractional reading. The dial is circular and has a pointer it is mounted on a toothed gear track which drives the pointer. The dial caliper has a fixed (main) scale and a movable dial, unlike the vernier caliper which has a second, movable vernier scale.

#Mitutoyo dial caliper series

The Mitutoyo 505 series dial caliper uses a combination of a vernier scale and a dial whose pointer travels one rotation for each 0.1” measured to perform precise outside diameter (OD), inside diameter (ID), depth, and step measurements. Models available with carbide-tipped OD and ID jaws.Lock screw for dial bezel and for holding the slding jaw position.Titanium Nitride (TiN) coating is applied to the sliding surface to increase wear resistance(except for 0-300mm and 0-12' model).New designed dial movement for ultra smooth sliding and high shock protection.
