Caliper (analog) högert technik HT4M270 150 mm measuring tool

högert technik HT4M270 analog caliper with a 150 mm measuring range is a mechanical vernier caliper designed for basic dimensional checks and routine inspection tasks. The metal construction gives a stable reference for external, internal and depth measurements. A main scale and a vernier scale provide readable results suitable for workshop, hobby or field use where standard precision is sufficient.

Advantages

The caliper's all-metal body ensures durability and consistent contact surfaces for repeatable readings. Its analog vernier scale does not require batteries, making it immediately ready for use and reliable in environments without power. Compact size and a clear graduated scale allow quick measurements of shafts, holes and depths with a standard resolution typical for vernier instruments.

Suitable for

• Measuring external diameters and widths in workshop and hobby projects
• Checking internal diameters of bores and recesses
• Measuring depths of grooves and steps
• Routine inspection and quick dimensional verification on-site

Key specifications

• Measuring range: 0–150 mm
• Display type: analog vernier scale
• Measurement functions: external, internal, depth
• Construction material: metal frame and jaws
• Typical accuracy class: standard vernier precision for quick checks

How to use

Before measuring, clean the jaws and the workpiece surface to remove dirt or debris that could affect accuracy. Close the jaws and check that the zero on the vernier aligns with the main scale; if not, note the zero error. For external measurements, gently close the jaws on the object without excessive force and read the value by combining the main scale and the vernier reading. For internal measurements, use the smaller jaws and align them inside the bore, then read the scales. For depth measurements, extend the depth rod into the feature to be measured and read the combined scale. Handle the caliper steadily and avoid twisting motions while taking readings.

Usage recommendations

Store the caliper in a protective case or dry place to avoid corrosion and mechanical damage. Periodically verify measurement accuracy against a gauge block or reference standard if precise control is required. Do not use the caliper as a pry tool or hammer and avoid exposing it to liquids or heavy contamination to preserve the vernier scale readability.
