Digital caliper Keltin Suwmiarka 150 mm — 150mm measuring jaw, electronic display

Digital caliper Keltin Suwmiarka 150 mm is a compact electronic measuring tool designed for metric linear measurements up to 150 mm. It features stainless steel measuring jaws and a clear electronic display that shows values in millimetres for external, internal and depth measurements. The caliper combines a sliding scale mechanism with an electronic readout for fast, repeatable readings, making it suitable for hobby, DIY, workshop and light professional tasks that require compact and accurate measurement.

Advantages

The caliper offers quick, direct digital readout for reduced reading errors and faster measurement cycles. Stainless steel jaws provide wear resistance and reliable contact with measured parts, while the slim sliding beam ensures smooth movement and precise positioning. The device is lightweight and portable, with a measuring range sufficient for many common small-part tasks and a design that supports metric-only readings for straightforward use.

Suitable for

• Measuring external dimensions of small parts and components
• Measuring internal diameters such as bores and slots
• Measuring depths of holes and recesses
• Hobby and DIY projects where compact metric measurement is needed
• Light workshop and inspection tasks for small assemblies

Key specifications

• Measuring range: 0–150 mm
• Measuring jaws: stainless steel for external and internal measurements
• Display: electronic digital readout in millimetres
• Measurement types: external, internal and depth
• Housing and beam: slim sliding profile for smooth operation

How to use

To measure an external dimension, open the jaws, position the part between them and gently close until contact is made; read the value from the electronic display. For internal measurements, use the smaller upper jaws, open them inside the bore or slot and read the displayed value. For depth measurement, extend the depth probe from the back of the slider into the hole or recess and read the depth on the screen. Before measuring, zero the display with the jaws fully closed to ensure accurate relative readings. Keep movement steady and avoid excessive force on the jaws to maintain measurement precision.

Usage recommendations

Store the caliper in a protective case when not in use, keep the jaws clean and dry to prevent corrosion, and replace the battery promptly when low display contrast or erratic readings appear. Avoid exposing the instrument to strong impacts, excessive dust or liquid immersion to preserve accuracy and prolong service life.
