Depth gauge M204.042 — Analogue vernier depth gauge, 0–300 mm, 0.02 mm (Metav IndustryLine)

Depth gauge M204.042 is an analogue depth measuring instrument for routine workshop and inspection tasks up to 300 mm, designed to deliver precise readings in accordance with DIN 862.

• Analogue vernier with 0.02 mm resolution
• Measuring range 0–300 mm for workshop use
• Stainless steel body, matt chrome scale and vernier
• Fine locking screw for repeatable readings
• Supplied in a protective case for transport

Dependable precision for standard workshop requirements

An analogue vernier calibrated to 0.02 mm (nonius 1/50 mm) provides a high level of mechanical accuracy suitable for fine metrology tasks. The instrument adheres to DIN 862, which sets clear expectations for dimensional gauges in industrial environments. With a measuring span of 0–300 mm, this tool sits in the standard caliper class — the preferred balance of reach and stiffness for most machining and metal‑working operations. The mechanical design avoids reliance on batteries, offering long‑term stability and straightforward maintenance while delivering repeatable depth readings.

Built materials and handling that suit daily use

Constructed from stainless steel with the scale and vernier matt chrome‑plated, the gauge withstands regular workshop exposure while remaining easy to read. A dedicated locking screw secures the slide for reproducible measurements and safe transport. The instrument is supplied in a protective case, ensuring safe storage and transport between job sites or on the shop floor. A 150 mm base/bridge provides a stable reference for depth measurement and supports consistent alignment against workpieces.

Simple operation with a precise mechanical readout

The vernier layout, specified as 1/50 mm, allows fast visual determination of the result: align the zero and read the vernier line that coincides with the main scale for the 0.02 mm increment. Compared with digital alternatives, the mechanical readout reduces susceptibility to electronic faults and offers immediate, intuitive readings for experienced operators. Proper handling — measured contact, clean reference faces and light, consistent seating of the base — ensures the mechanical precision is translated into reliable measurement data for quality control tasks.

Practical applications and workshop fit

This depth gauge is ideal for machine shops, toolrooms and metal‑fabrication plants where depth measurements must be robust and repeatable. As part of the standard 0–300 mm instrument set, it complements micrometres and callipers, covering tasks such as recess depth checks, slot depths and fixture set‑up. The combination of DIN 862 compliance, corrosion‑resistant materials and a secure locking mechanism supports efficient inspection routines and reduces rework caused by inconsistent measurement practice. The instrument is supplied as SKU M204.042 by Metav IndustryLine, reflecting a focus on accessible, durable metrology for everyday industrial use.

FAQ

How precise is the depth measurement with this instrument? The depth gauge M204.042 offers a mechanical resolution of 0.02 mm (nonius 1/50 mm) and meets DIN 862, delivering high repeatability suitable for precise workshop and inspection tasks.

Is the instrument suitable for harsh workshop environments? The M204.042 uses stainless steel with a matt chrome scale and vernier and is supplied in a protective case, which together improve resistance to typical workshop wear and help preserve measurement integrity.

Can this tool be used for measurements other than depth? This model is designed specifically as a depth gauge; its geometry and scale are optimised for depth measurement rather than external diameter or internal bore checks.

How is the vernier read and what does 1/50 mm mean? Read the main scale first, then add the vernier line that aligns with the main scale; 1/50 mm denotes the vernier subdivision that yields 0.02 mm increments for precise manual readings.

Does the instrument include a calibration certificate? The standard delivery does not include an ISO 17025 certificate; any specific calibration requirements should be verified at the point of order or through the product listing.
