Condition
Used (Excellent / Complete Set).
This digital caliper is in excellent used condition. While there are some cosmetic signs of workshop use on the body, the tool functions perfectly. The sliding action is smooth, and the jaws meet accurately with no light gap. It is a complete set, supplied in its original Mitutoyo plastic case with all original paperwork and the inspection certificate.
Product Overview
The Mitutoyo 500-197-30 is a standard-setting ABSOLUTE AOS Digimatic Caliper with an extended measuring range of 0 – 200mm (0 – 8″). This 8-inch model is preferred by many machinists over the standard 150mm (6″) version because it allows for the measurement of larger shafts, chuck backplates, and bolt circles without needing to switch to a different tool.
It features Mitutoyo’s AOS (Advanced Onsite Sensor) induction type encoder. Unlike older digital calipers that glitch if they get a little oil on the scale, this sensor is resistant to dirt, oil, and water droplets on the scale face, ensuring reliable readings in real-world conditions. It utilises the ABSOLUTE system, meaning you don’t have to zero the tool every time you turn it on—it remembers its position indefinitely.+2
