Digital Caliper Högert Technik HT4M274, measuring range 150 mm, metal body, digital readout

Digital caliper Högert Technik HT4M274 is a precision measuring tool with a 150 mm measuring range and a metal body. The device provides quick digital readout of external, internal and depth measurements, allowing accurate linear and step measurements for workshops, hobby projects and simple quality control tasks. The compact, robust construction combines a rigid metal frame with an electronic display for fast dimension reading and repeatable results.

Advantages

The metal body ensures durability and stiffness that support consistent measuring accuracy during routine use. The digital readout offers instant, easy-to-read numerical results which reduce reading errors compared with analog scales. A 150 mm measuring range covers the majority of everyday measuring tasks while the caliper’s compact size is convenient for storage and transport. The tool is suitable for straightforward, rapid measurement workflows thanks to its simple user interface and clear display.

Suitable for

• External diameter and length measurements of parts and workpieces
• Internal diameter checks for holes and bores
• Depth and step measurements for fittings and assemblies
• Hobbyist projects, model making and DIY metal/plastic work
• Basic workshop and incoming inspection tasks

Key specifications

• Measuring range: 150 mm
• Construction: metal body for improved rigidity
• Measurement types: external, internal and depth
• Display: digital electronic readout for direct numerical values
• Form factor: compact hand-held caliper suitable for bench and field use

How to use

Before measuring, ensure the jaws are clean and the display is zeroed with the jaws closed. For external measurements, position the workpiece between the main jaws and slide the movable jaw until light contact is achieved; read the value from the digital display. For internal measurements, use the smaller upper jaws and expand them inside the bore until they contact the walls, then read the displayed value. For depth measurements, extend the depth rod into the hole or recess and read the depth on the display. After use, wipe the caliper clean and store it in a protective case to preserve accuracy.

Usage recommendations

Avoid exposing the caliper to strong magnetic fields, excessive dust, or liquids. Handle the instrument with care to prevent shocks or drops that may affect calibration. Periodically check zero and compare measurements with a reference gauge to confirm ongoing accuracy.
