Prime-Line WORKPRO W066006 Electronic Caliper with Digital Display, SAE

Digital Caliper for Workshop Use

The WORKPRO W066006 electronic caliper provides a large LCD display that shows numeric values for fast, accurate readings. It converts between metric and inch units with a single button press and includes a zero function at any position. The tool is built from corrosion-resistant stainless steel for reliable performance across different climates. A thumb-wheel allows smooth adjustment during measurement tasks.

Practical Limits of the Vernier Interface

Accuracy is rated at 0.02 mm or 0.001 in across the full measuring range of 0 mm to 150 mm (0 in to 6 in). The digital readout depends on supplied button cell batteries and a manual on/off switch for power management. A thumbscrew lock holds a chosen measurement for transfer or recording. Three measurement modes are available: outside jaws, inside jaws, and a depth rod.

Capacity and Headroom for Common Tasks

The 150 mm range covers typical small-part dimensions such as fastener diameters, sheet thickness, and shallow hole depths. Outside jaws handle external widths, inside jaws capture internal diameters, and the depth probe reaches into recesses. The tool suits hobbyists and technicians needing quick, repeatable data without a steep learning curve. It is not suited for parts exceeding six inches or for applications requiring certified calibration traceability.
