vernier caliper

This Digital Vernier Caliper is a high-precision dimensional metrology instrument designed for accurate internal, external, depth, and step measurements in civil engineering testing, laboratory specimen preparation, and quality inspection. Built from durable, corrosion-resistant hardened stainless steel, it provides rapid dimensional verification of concrete test cubes, cylindrical cores, tensile rebar samples, and precision-machined testing apparatus components.

Featuring an ultra-lightweight 145-gram ergonomic body, the caliper is equipped with an easy-to-read digital LCD screen that provides dual-unit measurement across 0 to 150 mm (0 to 6 inches) with an instant inch-to-metric conversion toggle. The high-sensitivity sensor delivers precise direct readings down to 0.01 mm (0.0005 inch), supported by a smooth thumb roller, zero-reset capability at any position, and a thumb-locking screw to secure exact specimen dimensions for reporting and calibration.
