Traceable Calipers make length/diameter measurements three ways-outside, inside, and depth. At the touch of a button units switch from inches to millimeters. Made of durable acid resistant, hardened stainless-steel.

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 in. high.

To assure accuracy an individually serial-numbered Traceable Certificate is provided from an ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

No lubrication is ever required on the ultra-smooth slide bar. Runs on the supplied battery for 10,000 hours (replacement battery, Cat. No. 350-18940). Includes carrying case. Resolution: 0.0005 in. (0.01 mm). Accuracy: +/-0.001 in./in. (+/-0.03 mm/mm).
