Adafruit Solar Digital Calipers

Say goodbye to dead batteries at crucial moments; these calipers are powered by solar panels and include a battery backup for low-light conditions. The plastic jaws make them unsuitable for hot metal measurement but ideal for standard component checks.

Easily switch between millimeters and inches with a single button, making them versatile for various tasks. Just remember to zero them before use by closing the jaws and pressing the Zero button. The CR2016 backup battery is not included, but the calipers run smoothly on solar power when exposed to adequate light (over 200 lux).

Designed for sustainability, these calipers are perfect for measuring in well-lit areas or places where coin batteries are hard to find. Rest assured, if the light fades, the non-rechargeable 3V battery has you covered. Observe that the color of calipers may vary.
