150 mm measuring range

The Aurdeayi digital caliper covers 0 to 150 mm with 0.01 mm resolution and ±0.02 mm accuracy. It is suited for DIY enthusiasts, mechanics, woodworkers and jewelers who need repeatable internal, external, height and depth readings. The stainless steel body and large LCD give clear values during everyday workshop tasks. Buyers who need a longer range or a certified calibration report should look elsewhere.

Auto-off and battery care

Three LR44 cells ship installed with an insulating sheet that must be removed before first use. The tool powers down automatically after five minutes of inactivity to extend battery life. It is not waterproof and has no resistance to oil or liquids, so frequent wiping is recommended for reliable operation. No charging port or external power option is provided.

Inch/mm conversion button

A single button toggles between millimetre and inch readouts, showing 0.0005 inch resolution and ±0.001 inch accuracy. The knurled thumb roller and locking screw allow smooth sliding and fixed positioning while measuring. No software, data output or wireless link is included, so all readings must be recorded manually.
