Park Tool DC-3 Digital Caliper

The Park Tool DC-3 Digital Caliper is a precision measurement tool for bicycle workshop use designed for technicians who need accurate readings across a wide range of component dimensions. It measures external internal depth and stepped dimensions — covering common shop tasks such as identifying seat post diameters head tube dimensions bearing sizes and spoke gauges. The DC-3 reads in both metric and imperial units with a range of 150mm/6 inches and a resolution of 0.01mm/0.0005 inches displayed on a large LCD screen for clear at-a-glance readability. Accuracy is rated at +/-0.02mm/0.001 inches with repeatability of +/-0.01mm/0.0005 inches placing it firmly in the precision tier expected for professional service work.
