Description

Product Introduction:

The product features an open‑type ruler body that slides smoothly, making it easy to clean away metal shavings and oil residues and simplifying maintenance. The ruler is crafted from stainless steel, offering excellent rigidity, wear resistance, and dimensional stability. Dual measurement systems—both analog scale and digital display—ensure consistent, reliable accuracy.

Equipped with a large, high-definition digital display, it supports metric–imperial unit conversion, zeroing at any position, and data-hold functionality, ensuring simple operation and minimizing human‑induced reading errors. It also features a locking mechanism to secure readings, facilitating convenient recording and re‑verification.

Product Applications:

Suitable for a variety of workshop environments. With excellent overall rigidity, stable accuracy, and a comfortable grip, it is a commonly used basic measuring tool in industries such as machining, mold making, hardware, and automotive repair.

Product Features:

1 Suitable for left-handed users or situations where measurement can only be taken from the left side,

2. Zeroing at any position facilitates switching between relative and absolute measurements.

3. Metric–imperial conversion at any position.
