IP54 digital three-point internal micrometer is a precision measuring tool, which specially used for accurate measurement
of inner diameter size, and has a certain dustproof and waterproof ability, and adopts a three-point design to ensure the
accuracy and stability of measurement. The measurement results are displayed directly through the electronic display,
and the readings are intuitive and convenient, reducing human error.
An IP54 digital three-point internal micrometer is constructed as following parts:
1. Body: It provides the basis for support and positioning of other components, ensuring accurate measurements.
2. Measuring jaw: It usually consists of three small metal jaws that are able to move radially to contact the bore
being measured.
3. Extension bar: Extensions can be used to measure deep hole sizes, increasing the range and flexibility of the micrometer.
4. Digital display: The electronic digital display system can directly display the measurement results and improve
the measurement efficiency and accuracy.
5. Protection level: IP54 protection level means that the micrometer has a certain dustproof and waterproof ability,
and can be used in harsh environments.
Special features and design：
Three-point positioning: IP54 three-point inner diameter micrometer adopts three-point positioning technology, three anvils
are evenly spaced at 120° intervals and are pressed against the inner wall of the bore to determine the exact position of the
axis of the bore, which is suitable for precision measurement of blind holes and through holes. This design provides more stable
measurement results and reduces errors caused by changes in measurement position.
