Caliper INSIZE 1108-150W electronic vernier caliper with locking screw, measuring range 0–150 mm / 0–6"

Electronic INSIZE 1108-150W vernier caliper with locking screw is a precision measuring tool designed for linear measurements from 0 to 150 mm (0–6"). It provides digital readout for rapid, easy-to-read results and supports internal, external and depth measurements. The integrated screw clamp locks the jaw position to secure repeatable readings, making the caliper suitable for workshop tasks, quality control checks and engineering measurement needs.

Advantages

The digital display offers fast and clear measurement readout with improved accuracy compared to purely analog calipers. A locking screw holds the jaws in place for consistent repeat measurements and for transferring dimensions. The caliper's compact design and lightweight construction allow comfortable handling during extended use. It supports multiple measurement types (external, internal, depth) so a single instrument covers several tasks.

Suitable for

• External diameter and length measurements of parts and components
• Internal bore and slot width measurements
• Depth measurement of steps, holes and recesses
• Quality control inspection and dimensional verification
• Workshop setup, maintenance and prototype checking

Key specifications

• Measuring range: 0–150 mm (0–6")
• Measurement types: external, internal and depth
• Display type: digital LCD readout
• Locking mechanism: screw clamp for jaw fixation
• Construction: lightweight hand-held caliper body suitable for manual operation

How to use

Before measurement, ensure the caliper is zeroed with closed jaws and the display is set to the preferred unit (mm or inches). Open the jaws and place them around or inside the feature to be measured, or use the depth probe for depth readings. Tighten the locking screw to secure the jaw position when a fixed measurement is required or when recording repeatable dimensions. Read the value from the digital display and, if necessary, switch units or reset to zero for subsequent measurements.

Usage recommendations

Handle the caliper with care: avoid dropping or striking the instrument, keep measuring surfaces clean and free of debris, and store in a protective case when not in use. Periodically check zero calibration and replace batteries as needed to maintain reliable digital readout. Use the locking screw to stabilize readings during transfer or when measuring multiple identical parts.
