Precision measuring tool for workshop and DIY tasks, promising clear, repeatable readings from UEZNIRN Digital Caliper. For tradespeople and hobbyists, large digits and a robust stainless-steel body reduce frustration and speed up work. Is the accuracy and durability suited to everyday professional use?

⚡ At a Glance
  • Measurement Accuracy: Consistent readings across 0–150mm range with ±0.02mm precision
  • Best for: Mechanics, engineers and DIYers who need reliable, quick measurements
  • Not ideal for: Tasks requiring submersion-proof tools or finer-than-±0.02mm micrometrology

Stainless-steel caliper with 0–150mm range, large LCD and ±0.02mm precision. IP54 splash and dust protection suits workshop and field use.


Clear readings even in bright light – Thanks to Large LCD Display

Large, high-contrast LCD shows oversized digits for each measurement, designed to remain legible outdoors and under strong workshop lighting. The display reduces the need to peer closely at the scale.

Faster, less error-prone readings for routine checks and repeated measurements. Reduced eye strain when working on benches or on-site.

Long-term durability – With stainless-steel construction and precision polishing

Brushed stainless-steel body and a precision-polished finish resist corrosion and wear on the measuring jaws and rails. Robust materials preserve the sliding action and dimensional integrity over repeated use.

Maintains calibration and reliable operation in demanding environments. Suitable for regular workshop use without rapid wear.

Versatile measurement modes – With 0–150mm range, zero function and inch/mm conversion

Measurement range covers 0–150mm (0–6 inches) and supports inside, outside, depth and step readings. A zero button allows relative measurements from any point and a unit switch toggles between millimetres and inches.

Useful for a wide range of parts and setups, from setting jigs to checking component dimensions. Quick unit switching avoids manual conversions when working from mixed drawings.
