The Mitutoyo Digimatic Holtest digital internal micrometer sets with interchangeable heads includes complete gages (display units and measuring heads) for each measurement size in the set. All of the holtest units feature self-centering Titanium Nitride (TiN) coated contact points that provide accurate, sensitive measurements and are highly durable. Precision-machined gears ensure reliable, repeatable measurements that are shown on a large, easy-to-read LCD display in an impact and water resistant housing. The holtest’s ratchet stop mechanism provides a constant measuring force on the hardened-steel spindle to ensure accurate, even measurements.
