DeWesser Precision Stainless Hardened Measuring Calipers - Digital LCD & Standard Manual Vernier Models (6" / 150mm & 8" / 200mm)
-
The DeWesser® Precision Caliper Series is engineered for high-accuracy outer, inner, depth, and step dimensional measurements in metalworking, machining, engineering, and quality control applications. Constructed from hardened stainless steel, this range includes both high-precision Digital Calipers (featuring clear LCD screens and 0.02 mm resolution) and traditional Mechanical Vernier Calipers (offering 0.05 mm accuracy). Available in two standard measuring ranges: 0–150 mm (6 inch) and 0–200 mm (8 inch). Designed with precision-ground measuring jaws, a thumb-roll fine adjustment, and a knurled locking screw for secure measurement transfer.

Key Features & Standards
-
Hardened Stainless Steel Construction: Precision ground and hardened to maintain structural accuracy and resist physical wear over time.
-
4-Way Measurement Versatility: Supports external OD, internal ID, step height, and deep bore depth readings with integrated probes.
-
Digital Accuracy (Digital Series): High-contrast digital LCD screen provides 0.02 mm precision, reducing parallax reading errors.
-
Clear Laser-Etched Scales (Vernier Series): High-visibility dual graduations enable accurate manual readings down to 0.05 mm.
-
Thumb Roll & Position Lock: Integrated thumbwheel ensures smooth jaw gliding and a top thumb screw locks the slider position for fixed verification.
⚠️ Safety Warning: Keep measuring jaws clean and free from metal burrs, oil, or grit before testing. Do not apply excessive force when closing jaws on workpiece surfaces to prevent damaging the fine measuring edges. Store digital units with power off in a dry protective case.
