Caliper INSIZE 1312-150A 150 mm, 0.02 mm, dial indicator, model SUWMIARKA MAUA-Z

INSIZE 1312-150A caliper is a 150 mm precision measuring instrument with a 0.02 mm resolution and an analogue dial indicator for straightforward readout. It is designed to measure external dimensions, internal diameters and depths across a 150 mm range. Built for workshop and inspection environments, the caliper combines a hardened measuring surface with a clear dial to support repeatable linear measurements in metalworking, quality control and general mechanical tasks.

Advantages

The dial-equipped caliper delivers quick analogue feedback while maintaining fine resolution of 0.02 mm, enabling precise incremental readings without relying solely on digital electronics. Robust construction and hardened jaws provide wear resistance for repeated use in workshop conditions. The 150 mm measuring range covers common small- to medium-size parts, and the instrument’s simple mechanical design offers reliable performance with minimal maintenance.

Suitable for

• Measuring external dimensions of machined parts
• Checking internal diameters and bore sizes
• Depth measurement of slots and steps
• Quality control and inspection in metalworking
• General workshop and maintenance measurement tasks

Key specifications

• Measuring range: 0–150 mm
• Resolution: 0.02 mm
• Readout type: Analogue dial indicator
• Measurement functions: External, internal and depth
• Construction: Hardened measuring faces and rigid beam

How to use

Clean the measuring faces and the object surface before measurement to avoid debris affecting accuracy. Close the jaws gently on the part for external measurements, insert the inside jaws for internal checks or use the depth rod for depth measurements. Read the main scale and the dial indicator to determine the measurement with 0.02 mm increments. Apply light, consistent measuring force and avoid tilting the tool to prevent parallax or misalignment errors.

Usage recommendations

Store the caliper in a protective case when not in use, keep it dry and free from coolant or cutting fluids, and periodically check for wear on the jaws. Calibrate or verify accuracy against gauge blocks or a reference standard at regular intervals appropriate for your quality procedures.
