Caliper INSIZE 150 mm model 1205-150S, 0.05 mm resolution, 6-scale

The INSIZE 150 mm caliper model 1205-150S is a compact precision measuring tool with 0.05 mm resolution and a six-scale display, designed for accurate linear measurements up to 150 mm. It supports external, internal and depth measurements, providing reliable dimensional checks for parts and assemblies in workshops, quality control labs and engineering environments. The caliper's compact form factor and clear scale arrangement make it suitable for routine inspection and measurement tasks where space and repeatability matter.

Advantages

This INSIZE caliper offers fine resolution of 0.05 mm for improved measurement accuracy compared with coarser analog tools, while the six-scale format enhances readability and rapid interpretation of results. Its construction supports three measurement modes—external, internal and depth—so a single instrument covers multiple tasks. The 150 mm measuring range balances portability with sufficient capacity for many common components, and the robust design is appropriate for frequent shop-floor use.

Suitable for

• External diameter and length checks of machined parts
• Internal bore and groove measurements
• Depth measurements of slots, steps and recesses
• Routine quality control inspection and incoming goods checks
• Engineering and prototype measurement in workshops

Key specifications

• Measuring range: 0–150 mm
• Resolution: 0.05 mm
• Display type: six-scale readout for precise analogue interpretation
• Measurement functions: external, internal and depth
• Construction: compact caliper body suitable for workshop use

How to use

Hold the caliper body firmly and slide the jaws to the approximate measurement position. For external measurements, place the object between the outer jaws and close the jaws until they contact the surfaces; for internal measurements, use the inner jaws and expand until they contact the bore; for depth measurements extend the depth rod into the feature and read the scale. Use the six-scale readout to determine the value with 0.05 mm resolution, ensuring the instrument is perpendicular to the measured surface and the jaws are seated without excessive force. Keep movements steady and re-zero or calibrate before critical measurements.

Usage recommendations

Store the caliper in a protective case when not in use, avoid exposure to strong impacts or corrosive environments, and periodically check calibration to maintain accuracy. Clean measuring faces before and after use and operate the sliding mechanism gently to prolong service life.
