Our precision measuring instruments require basically no servicing.
Nevertheless, to assure a long-service life for your MICROTEST® Internal Micrometer, we recommend that the device is always kept clean. If it becomes soiled by cooling water or particles of dirt, it is enough to just wipe the instrument down with a cloth to prevent unnecessary malfunctions that result if moving parts stick.
Repair or overhaul is only due after between 7 to 15 years.
