## Long description

Digital Micrometer INSIZE 5–30 mm, model 3520-30 is a precision handheld instrument designed for accurate external dimensional measurements. The tool provides a clear digital readout for quick reading of thicknesses and diameters within the 5–30 mm measuring range. It is intended for use in workshops, quality control and mechanical engineering environments where repeatable and reliable measurement of small external features is required.
Advantages
The digital display ensures fast, unambiguous readings and reduces human error compared with analog scales. The compact micrometer frame and smooth spindle movement allow stable contact and consistent measurement force. Durable construction and a calibrated measuring face provide reliable performance for routine inspection tasks. Battery-powered digital electronics offer portability and immediate measurement results without manual interpretation.
Suitable for
 Measuring external diameters of shafts and pins
 Checking thickness of sheet metal, plates and components
 Routine workshop inspections and in-process quality control
 Mechanical engineering and assembly tolerance checks
Key specifications
 Measuring range: 5–30 mm
 Type: digital outside micrometer for external measurements
 Resolution: high-precision digital readout (typical 0.01 mm resolution)
 Measuring faces: hardened and ground anvils for wear resistance
 Spindle: precision screw with smooth travel for consistent contact
 Power source: battery-operated digital electronics

How to use
Bring the measuring faces close to the object and rotate the thimble or ratchet until the spindle contacts the workpiece. Use the ratchet stop or friction thimble where provided to apply consistent measuring pressure. Read the measurement directly from the digital display and, if necessary, zero the instrument on a reference surface before measuring. Clean the measuring faces and the workpiece contact area before each measurement to avoid inaccuracies caused by debris.
Usage recommendations
For best results, store the micrometer in a protective case when not in use, replace the battery promptly when display dimming occurs, and calibrate periodically according to your quality procedures. Avoid exposing the instrument to strong shocks, extreme temperatures, or high humidity to maintain measurement accuracy.
