External Analog Micrometer Gimex 0–25 mm model 304.408

Analog external micrometer Gimex 0–25 mm model 304.408 is a compact handheld measuring instrument designed for precise outside diameter and thickness measurements within the 0–25 mm range. The micrometer uses a mechanical thimble and spindle to provide direct reading of linear dimensions with fine resolution, making it suitable for routine dimension checks in workshops, quality control and metalworking environments.

Advantages

This micrometer delivers reliable mechanical measurement without batteries, offering durability and consistent readings in typical workshop conditions. Its compact design allows easy handling and access to small or confined parts. The mechanical thimble provides tactile feedback and a clear graduated scale for straightforward reading of measurements. Built with materials suited to industrial use, it resists everyday wear and supports repeated inspection tasks.

Suitable for

• Measuring external diameters of shafts, pins and rods
• Checking thickness of sheet metal and machined components
• Routine inspection and quality control in small workshops
• Dimension verification during machining and assembly operations

Key specifications

• Measurement range: 0–25 mm
• Type: external analog micrometer
• Reading system: mechanical thimble and spindle with graduated scale
• Instrument format: compact handheld body for accessibility
• Typical applications: outside diameter and thickness measurement

How to use

Place the object between the spindle and anvil, then gently rotate the thimble until the spindle contacts the workpiece using the ratchet or friction stop if present to avoid over-tightening. Read the main scale and the thimble graduation to determine the measurement value, combining the millimetre scale and the thimble division according to the instrument markings. For repeatable results, ensure flat, clean measuring faces and stable positioning of the workpiece before taking the reading.

Usage recommendations

Store the micrometer in a protective case when not in use, keep measuring faces clean and periodically check calibration against gauge blocks or a reference standard. Avoid exposing the instrument to strong shocks, corrosive environments or large temperature variations to maintain accuracy.
