Digital calipers

Traceable digital calipers from the Control Company, Friendswood, Tex, make length/diameter measurements two ways—outside and inside. Digital display models measure to 6 inches (150mm). Resolution is 0.01 inch/0.1mm. Accuracy is ±0.01 inch or ±0.2mm. At the touch of a button, units switch from inches to millimeters. Zero button instantly sets unit to zero when jaws are at any position. This permits setting a floating zero or reference point to read greater-than or less-than results with a minus sign displayed without calculations. Ergonomic precision calipers are designed for measuring the outside diameter of stoppers and the inside diameter of tubing. Easy-to-read jumbo digital display is 1/3-inch high. No lubrication is ever required on the slide bar. The calipers run on the supplied battery for 10,000 hours.
