Solar Digital Caliper 150mm - plastic

The Solar Digital Caliper 150mm is a versatile and environmentally friendly precision instrument designed for accurate measurement across a wide range of applications. Manufactured from high-strength plastic, the caliper is lightweight, non-magnetic, and resistant to rust and corrosion, making it especially suitable for use in workshops, laboratories, and field environments where metal calipers may not be ideal.

A standout feature of this tool is its dual power system: a built-in solar panel automatically powers the display when ambient light exceeds 200 LUX, while a 3V backup battery kicks in seamlessly during low-light conditions. This hybrid energy design dramatically extends battery life and ensures continuous operation in any working environment.

The caliper supports four measuring modes — outside, inside, step, and depth — making it a complete dimensional measurement solution. It offers a measuring range of 0 to 150mm (6 inches) with an accuracy of ±0.2mm and a resolution of 0.1mm / 0.01". The large, easy-to-read LCD display shows measurements in both metric and imperial units, with instant conversion at the press of a button. A zero-setting function allows for relative measurements at any position along the scale.

Designed for stable and accurate readings, the caliper supports a maximum measuring speed of 1.5mm/second and operates reliably in temperatures from 0°C to +40°C, with humidity tolerance up to 80% RH. Its compact dimensions (235 × 75 × 10 mm) make it easy to carry and store.
