Mitutoyo 500 Series [500-774] Digital ABSOLUTE Super Solar Caliper 0-150mm

The The Mitutoyo 500 series Super Caliper is a solar-powered digital caliper made of durable hardened stainless steel using Mitutoyo’s ABSOLUTE linear encoder technology. Its impact-resistant display helps increase durability and IP67 protection helps ensure waterproof reliability. These calipers have no need for origin setup and can be used in any location, including dimly lit areas, and can be operated without replacing batteries.

Digital solar calipers have an LCD that displays in inch or metric units, to help increase readability. In environments with available light of 60 Lux or more, the caliper can immediately start measuring, even uncharged, without zero resetting, and operating speed is unrestricted.

The 500 series of Super Caliper has the ABSOLUTE electromagnetic induction linear encoder to help prevent overspeed errors. It measures outside diameter (OD), inside diameter (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. LCD resolution is 0.01 mm, repeatability is 0.0005”/0.01 mm, and accuracy is rated + or - 0.02 mm. It is Ingress Protection 67 (IP67)-certified, which means that the electronic components are resistant to debris and to submersion in liquid under standard conditions for up to 30 minutes. An alarm alerts the user to counting value composition errors. A rolling thumbwheel makes fine adjustments and a thumbscrew locks the scale’s position. Response speed is unlimited. The caliper can be used continuously above 60 Lux ambient illumination. The built-in solar cells can store energy for up to one hour of caliper operation in 50 Lux light.

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.
