Micrometer INSIZE MIKROMETR 125-150 STANDARD measuring tool 125–150 mm

INSIZE MIKROMETR 125-150 STANDARD measuring tool 125–150 mm is a precision outside micrometer designed to measure external dimensions in the 125–150 mm range. Built for workshop and inspection tasks, this micrometer provides accurate linear readings of shafts, bars and finished parts. It includes a calibrated spindle scale and a repeatable contact-pressure mechanism (ratchet or friction stop) to help obtain consistent results during series measurements.

Advantages

The micrometer delivers reliable accuracy for mechanical and metalworking applications thanks to its precisely ground anvil and spindle. The calibrated thimble and sleeve scale enable straightforward reading of measurements. Its repeatable contact-pressure mechanism reduces reading variance between operators. The robust frame and fine adjustment mechanism are designed for stable performance in routine inspection and workshop environments.

Suitable for

• Measuring external diameters of shafts and pins
• Checking thickness of bars and flat parts
• Dimensional inspection during quality control
• Precision setups in metalworking and machining

Key specifications

• Measuring range: 125–150 mm
• Type: outside micrometer for external measurements
• Contact faces: hardened and ground anvil and spindle
• Graduation: calibrated spindle/thimble scale for linear reading
• Contact-pressure mechanism: ratchet or friction stop for repeatable pressure
• Frame: rigid C-frame designed for stability during measurement

How to use

Place the part between the anvil and spindle, then turn the thimble until the contact faces touch the workpiece. Use the ratchet or friction stop to apply consistent contact pressure and avoid over-tightening. Read the measurement from the sleeve and thimble scale according to standard micrometer reading procedure. For best accuracy, measure at multiple points if the part may be tapered or out of round, and average the readings if required.

Usage recommendations

Keep the anvils clean and free of debris before each measurement, and store the micrometer in its protective case when not in use. Periodically check calibration against gauge blocks or a reference standard and avoid sudden temperature changes—allow the instrument and workpiece to reach the same ambient temperature to minimize thermal measurement errors.
