Product Overview
The Mitutoyo 500-151-30 is the industry-standard “Digimatic” digital caliper, widely regarded as the most reliable measuring tool for general workshop and engineering use. With a measuring range of 0 to 150mm, it features Mitutoyo’s patented AOS (Advanced Onsite Sensor) electromagnetic induction type encoder. This sensor technology is a significant upgrade over older capacitive models, as it is largely immune to environmental contaminants such as cutting oil, water, and dust that often cause measurement errors on standard digital calipers. The caliper utilises the Absolute (ABS) scale, meaning the origin point is set once and stored, removing the need to zero the instrument every time it is switched on. It also features a thumb roller for precise, controlled adjustment and a flat depth bar for measuring holes and recesses.
