Precision Measurement Tool
This digital vernier caliper provides internal, external, depth and step readings in millimetres and inches. A linear capacitive measuring system delivers a resolution of 0.01mm or 0.0005in with an accuracy of ±0.02mm. The 150mm measuring range suits workshop, automotive and household tasks.
Power and Durability
A single 1.5V SR44 silver oxide cell powers the large LCD display and an auto-off function conserves energy during pauses. Hardened stainless steel construction contains no plastic parts and resists water, dirt and oil. The instrument is calibrated for repeatability of 0.01mm across the full range.
Workshop Ready
The caliper fits into a sturdy plastic case alongside a spare LR44 battery and a mini screwdriver for quick changes. A knurled thumb roller and locking screw allow fast, secure jaw positioning. Zero setting at any position simplifies differential checks without extra accessories.

Questions about this item
How do I install the SR44 battery and what step is often missed?
Open the battery compartment with the included mini screwdriver, insert the 1.5V SR44 cell with correct polarity, then close the cover securely; the step often missed is tightening the screw fully so the seal stays water- and oil-resistant.
What maintenance will this caliper need later?
Clean the measuring faces with cotton after each use, apply a light coat of butter or oil if stored long term, and replace the SR44 battery when the large LCD display dims; a spare LR44 cell and screwdriver are already in the case.
What limit appears first during sustained measuring sessions?
The auto-off feature powers the tool down after a period of inactivity to save the 1.5V SR44 battery, so the first limit you hit is the automatic shutdown rather than any mechanical wear.
