Description

Product Introduction:

The digital vernier depth gauge is a precision measuring instrument used for measuring depths, step heights, groove depths, and hole depths. Featuring a direct‑read digital display, it provides clear, intuitive readings and significantly boosts measurement efficiency. The device is equipped with a high‑resolution LCD screen and offers one‑touch conversion between metric and imperial units, zeroing at any position, and data hold functionality, ensuring simple operation and minimizing human‑induced reading errors. Its base is wide and flat, providing a stable and reliable measurement reference; the body is made of stainless steel, offering excellent rigidity, resistance to deformation, and superior wear and corrosion resistance.

Product Applications:

Widely used in machining, mold making, automotive components, hardware, electronics, and other industries, it is ideal for rapid measurement of workpiece dimensions such as depth, step height, and groove width, serving as a fundamental precision measuring tool commonly employed in workshops and quality‑inspection processes.

Product Features:

1. Used for precise measurement of hole depth and step height;

2. Set the zero point at any position, facilitating conversion between relative and absolute measurements;

3. Switch between metric and imperial units at any time.
