How to Use Calipers
Battery Hack TutorialProduct Overview
No workbench is complete without a reliable set of calipers. Whether you are measuring a PCB footprint or sorting mixed-up screws, "eyeballing it" just doesn't cut it. These premium digital calipers are the exact same ones we use daily here at SparkFun. They feature a hardened stainless steel construction for durability and a smooth slide action that feels precise in the hand.
Precision Measurement
Gone are the days of squinting at vernier scales. The large LCD on these calipers provides instant, easy-to-read measurements in a selectable choice of units.
- Dual Mode: Switch instantly between millimeters and inches with a single button.
- High Resolution: Measures with a resolution of 0.01mm (0.0005") and an accuracy of ±0.02mm (for measurements <100mm), giving you confidence in your design tolerances.
- Standard Range: Capable of measuring internal, external, and depth dimensions up to 6 inches (150mm).
Power Smart
To ensure they are ready when you reach for them, these calipers feature an auto-shutoff function that conserves battery life after a period of inactivity. They run on a standard 1.5V LR44 button cell, and we've included two batteries in the package (one installed, plus a spare) so you are set for whatever you'll need to measure far into the future.
