Mitutoyo 0-150 mm Absolute Digimatic Depth Gauge is made with high-quality metal that lasts for a long time. The 0-150 mm Absolute Digimatic Depth Gauge's base and measuring faces are hardened and micro-lapped. The Digimatic Depth Gauge consists of an LCD that operates on a replaceable battery, measuring rods and scales. The depth Gauge scale accurately measures the length of the depth from the surface and converts the inches measurements to mm. The least count of the depth gauge is around 0.02 millimetres. The large, distinctly marked values on the scale are easily visible to users, making it very reliable and accurate.
