Caliper Mitutoyo analog 150 mm (6") measuring range, 0.05 mm resolution

Analog caliper Mitutoyo with 150 mm (6") measuring range and 0.05 mm resolution provides straightforward, mechanical measurement of external, internal, depth and step dimensions. The vernier scale design delivers direct readout without batteries or electronic components, while the robust metal construction is intended for regular use in workshops, inspection benches and field checks. This caliper is a simple precision tool for users who need reliable manual measurement and quick dimensional verification.

Advantages

The Mitutoyo analog caliper combines a clear vernier scale with a durable metal body to ensure consistent repeatability and resistance to workshop wear. Its 150 mm measuring range covers common small-part inspections, and the 0.05 mm scale division allows finer manual reading than coarser analog models. The absence of electronics reduces maintenance needs and eliminates battery dependence, while the sliding mechanism and locking screw enable stable readings during measurement procedures.

Suitable for

• General workshop measurements of shafts, pins and housings
• Inspection and quality control of small machined parts
• Measuring internal diameters, external diameters, depths and steps
• On-site checks where simple, robust tools are preferred

Key specifications

• Measuring range: 0–150 mm (0–6")
• Resolution / scale division: 0.05 mm
• Measurement functions: external, internal, depth, step
• Construction: metal body with sliding vernier
• Readout type: mechanical vernier scale (no electronics)
• Locking mechanism: adjustable locking screw for stable readings

How to use

Before measuring, clean the jaws and the object to remove debris or oil that could affect accuracy. Close the jaws and check the zero position on the vernier scale; if necessary bring the jaws to contact and verify alignment. For external measurements, place the outside jaws on the part and slide until contact is firm, then tighten the locking screw and read the vernier scale. For internal measurements, use the inside jaws and expand until contact is made with the internal faces. For depth and step measurements, use the depth blade or step faces by sliding the carriage until the measuring surface contacts the reference. Read the main scale and vernier division to determine the value to the nearest 0.05 mm.

Usage recommendations

Store the caliper in a protective case when not in use, avoid exposure to heavy impacts and excessive humidity, and periodically clean and lightly lubricate the sliding surfaces. Use gentle, consistent force when measuring to maintain repeatability and verify calibration against a gauge block or reference standard if high accuracy is required.
