Three-point contacts for self-centering measurement of the inside dimension (ID) of bores
Digital, single-value readout LCD displays in metric units for readability
Statistical Process Control (SPC) output transmits results to a computer or external device through an interface cable (sold separately)
Rated IP65 for resistance to penetration by dust and liquid up to the force of a low-pressure water jet
TiN coating on measuring faces helps provide wear resistance
The Mitutoyo 468 series Digimatic Holtest LCD inside micrometer has three-point contacts for self-centering measurement of the inside dimension (ID) of bores, and a digital single-value LCD readout that displays in metric units with resolution to 0.001mm. It also has Statistical Process Control (SPC) data output to transmit results to a computer or external device through an interface cable (sold separately).
The micrometer’s electronic microprocessor can hold measurements at any position, convert to absolute value, set a temporary zero position, and return to a true zero reading. An automatic off function helps preserve battery life when the unit is not in use. The electronics housing has an Ingress Protection 65 (IP65) rating, which means that components are resistant to penetration by dust and debris, and resistant to penetration by liquids and coolant up to the force of a low-pressure (to 30 kilonewtons/meter-squared) water jet. The measuring faces are made of hardened steel are TiN-coated for wear resistance. The micrometer includes, and is powered by, a single SR44 silver oxide battery, and comes with a fitted case for storage.
