The Mitutoyo Digimatic Holtest digital internal micrometer features self-centering anvils evenly spaced at 120° with contact points coated in Titanium Nitride (TiN) to provide accurate, sensitive measurements that 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.
