Dasqua External Electronic Caliper Gage is designed to measure outside dimensions (OD) with an accuracy of 0.0008"/0.02mm and a resolution of 0.0005"/0.01mm. It features a digital single-value readout LCD screen, which displays both inch and metric units for versatility when measuring. The device has absolute and incremental modes for taking intermediate or differential measurements, and stores a preset reference for comparing measurements. It is spring-loaded in the measuring direction for a consistent measuring force and improved measurement repeatability. A thumb lever retracts the movable point, and the caliper has a 2"/5cm diameter plastic electronic housing, steel arms, and hardened steel contact point for durability.
