An internal micrometer is a measuring tool used to measure the internal dimensions of parts (holes, grooves, etc.) where it is difficult to obtain accurate results using a ruler or caliper.
To take a measurement, the internal caliper is placed on or inserted into the part (tubes, spherical holes, etc.). The results are read using a ruler, dial, digital display, or vernier scale, depending on the type of internal caliper you are using.
Our website features several types of internal micrometers manufactured by MICROTECH.
The most popular internal micrometers include Indicator (indicator internal micrometers, digital indicator internal micrometers, high-precision indicator internal micrometers) all of which work on the same principle, the only difference being the measurement accuracy from 0.01 mm to 0.001 mm and different indicator heads, which are divided into analog and digital.
A micrometric internal micrometer is an internal micrometer that is used to take more accurate measurements of holes using the absolute method and has replaceable extensions.
Two-point and three-point micrometric internal gauges can be considered the most accurate instruments with a division price of 0.001 mm and small measurement ranges.
Lever internal micrometers are used for measurement by comparison using a two-point measurement scheme. This universal device has both an indicator and a digital scale, and its quick results and ease of use are among the undeniable advantages of this type of internal micrometer. Below is a range of internal micrometers manufactured by CHNPP "MICROTECH".
Our advantages: all internal micrometers are listed in the State Register of Measuring Instruments of Ukraine, have their own individual serial number, and are supplied with a passport and factory calibration.
