Caliper INSIZE 150 mm 0.02 mm resolution model 1205-1501S

INSIZE 150 mm caliper model 1205-1501S is a precision measuring tool designed for external, internal and depth measurements with a 150 mm measuring range and 0.02 mm resolution. The caliper combines robust measuring jaws, a compact body and a clear scale to enable accurate length, diameter and depth checks on metal and plastic parts in workshop and inspection environments. Its construction supports routine dimensional verification and small-part inspection where repeatable accuracy is required.

Advantages

The caliper provides high-resolution readings down to 0.02 mm for precise measurement results. Its rigid jaws and stable slide reduce flex and improve repeatability during contact measurements. The compact design and clear scale readout simplify handling and visual verification, while the tool’s compatibility with external, internal and depth measuring tasks makes it versatile for general workshop use. The overall construction is intended to withstand normal shop conditions and deliver consistent dimensional checks.

Suitable for

• Measuring external diameters and lengths of shafts and parts
• Checking internal diameters of holes and bores
• Measuring depths of slots, recesses and steps
• Routine inspection and quality control in small workshops
• Dimensional verification of metal and plastic components

Key specifications

• Measuring range: 150 mm
• Resolution: 0.02 mm
• Measurement functions: external, internal and depth measurements
• Jaws: robust contact jaws suitable for metal and plastic
• Display: clear scale readout for easy visual reading
• Design: compact and ergonomic for hand-held use

How to use

Before taking measurements, ensure the jaws are clean and the sliding mechanism moves smoothly. For external measurements, close the jaws around the workpiece and read the value from the scale. For internal diameters, use the smaller jaws and expand them until they contact the bore walls, then read the measurement. For depth measurement, extend the depth rod into the feature and read the value once the base of the caliper sits flat on the reference surface. Make sure to hold the caliper steady and perpendicular to the measured surface to reduce measurement error.

Usage recommendations

Store the caliper in a protective case when not in use, keep measuring surfaces clean and avoid applying excessive force on the jaws. Periodically check calibration against a gauge block or reference standard to maintain accuracy. Use consistent measuring technique and stable fixturing for repeatable results.
