Caliper Topex 150 mm 0.05 mm measuring tool

Handheld caliper Topex 150 mm 0.05 mm measuring tool is a compact, manual measuring instrument designed for linear external and internal measurements as well as depth checks. With a 150 mm measuring range and 0.05 mm resolution, this caliper delivers metric readings suitable for workshop, hobby, and inspection tasks where moderate precision is required. The tool is intended for simple, repeatable dimensional checks of shafts, holes and small parts.

Advantages

The Topex caliper combines a user-friendly sliding mechanism with a clear vernier scale that provides 0.05 mm resolution without electronics. Its 150 mm range covers most common small-part measurement needs while remaining lightweight and easy to handle. The caliper’s metal construction offers durability for frequent use in workshop conditions and the movable depth rod enables quick measurement of recesses and step depths.

Suitable for

• Measuring external dimensions of shafts, rods and profiles
• Checking internal diameters of holes and bores
• Depth measurement of recesses, slots and steps
• Workshop checks, hobby projects and general inspection tasks

Key specifications

• Measuring range: 150 mm
• Resolution: 0.05 mm
• Measurement types: external, internal, depth
• Scale type: vernier (mechanical)
• Material: metal body and jaws

How to use

Place the caliper jaws around or inside the feature to be measured and slide the movable jaw until it contacts the part with gentle, consistent pressure. For depth measurements, extend the depth rod from the end of the caliper into the recess and slide the main body until the rod reaches the bottom. Read the main scale and vernier alignment to determine the measurement to 0.05 mm resolution. Keep the jaws clean and avoid excessive force to maintain accuracy.

Usage recommendations

Store the caliper in a dry, protected case to prevent corrosion and mechanical damage. Before each use, wipe the measuring faces clean and verify zero alignment by closing the jaws gently; if zero reading is off, note the offset when recording measurements. For improved repeatability, support the workpiece and caliper steadily and avoid tilting the jaws during measurement.
