Micrometer accuracy comparison

The technical difficulty of the three-jaw inner diameter micrometer lies in the gap between the measuring jaws. The larger the gap between the measuring jaws, the greater the measurement error.

1. Full contact measurement on the measuring surface and 0-mark alignment
2. 3/1 measuring surface contact measurement deviation 0.04mm

Shanghai Hengliang brand, small gap between measuring jaws and small measurement error.

Differential roller flower design, comfortable to rotate. Ratchet force measuring device ensures accuracy.

The high-precision screw rod measures the precise inner hole, and the measuring surface is inlaid with carbide, which is wear-resistant and durable.

6-12 specifications are for parallax-free readings, and parallax-free readings are more accurate.
