3 Point Digital Inside Micrometer 16mm - 20mm
SERIES 361

A precision measuring instrument designed to measure the internal dimensions of bores, holes, and other cylindrical spaces with a high degree of accuracy. Unlike traditional micrometers, which measure external dimensions, this tool specializes in gauging internal diameters. The digital display provides an easy-to-read measurement, improving accuracy and reducing the chances of human error.

Resolution: 0.001mm/0.00005"
IP65 protection level
Button: on/off, set, mm/inch, ABS/INC, data output
Automatic power off
Data output
Ratchet stop
Carbide measuring faces (over 12mm series)
Extension rod are included
Setting rings are included (Range < 100mm)

How it works:

Three-point contact: The micrometer has three measuring points that evenly distribute pressure on the inner surface of the hole, ensuring accurate and repeatable measurements.
Digital display: The measured diameter is displayed digitally, eliminating the need for manual reading and reducing the possibility of errors.
Extension rods: These can be used to measure deeper holes.

Applications

Machining and Metalworking: Used to measure the internal diameters of bores and holes in metal components, ensuring that they meet the required specifications.
Quality Control: Essential in inspection processes to verify the accuracy of internal dimensions in manufactured parts.
Engineering: Applied in various engineering tasks where precise internal measurements are critical, such as in the design and fabrication of mechanical parts.
Automotive and Aerospace Industries: Used for measuring the internal diameters of engine cylinders, bearing races, and other critical components that require precise tolerances.

Usage Procedure

Select the Appropriate Measuring Head: If the micrometer comes with interchangeable heads, choose the one that matches the range of the bore to be measured.
Zero the Micrometer: Set the micrometer to zero using a calibrated ring gauge or setting standard.
Insert into the Bore: Carefully insert the measuring head into the bore, ensuring that the three-point contacts are aligned with the bore&s axis.
Expand the Measuring Points: Use the thimble to gently expand the measuring points until they make firm contact with the bore walls.
Read the Measurement: Observe the digital display for the internal diameter measurement. Ensure that the micrometer is properly centered in the bore for an accurate reading.
Record or Transfer Data: Record the measurement manually or transfer it to a connected device if using the data output feature.
