Control Control Company Traceable Digital Calipers - Traceable Digital Caliper - 3415

Designed for the lab - Traceable® Calipers make length/diameter measurements three ways#outside, inside, and depth. Digital display models measure to 8-inches (200mm). At the touch of a button units switch from inches to millimeters. Zeroes at any point - Zero button instantly sets unit to zero when jaws are at any position. This permits, without calculations, setting a Floating Zero# or reference point to read "greater than or less than results with a minus sign displayed". Ergonomic design precision calipers are ideal for measuring the outside diameter of stoppers, the inside diameter of tubing, and the depth of vials. Depth bar extends from the end of caliper. Fine adjustment thumb roller improves reading speeds and position-holding lock screw sets length. Easy-to-read jumbo digital display is 1/3-inch-high.
