The Mitutoyo 395 series LCD tube micrometer has a vertical anvil for measuring tubing wall thickness. It also has a digital single-value LCD readout that displays in inches and metric units with resolution to 0.00005” (0.001mm) for outside diameter (OD) measurement, and Statistical Process Control (SPC) data output to transmit results to a computer or external device. The output jack transmits SPC results to a computer through an interface cable (sold separately).
The micrometer’s electronic microprocessor can hold measurement at any position, convert to absolute value, set a temporary zero position, and return to a true zero reading. 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 spindle has a flat measuring face that is carbide-tipped for wear resistance. The vertical anvil may be a pin, spherical, or cylindrical type. The micrometer’s ratchet-stop mechanism helps provide uniform pressure during adjustment for precise, repeatable measurement. A spindle lock helps provide secure locking of the measurement position. The micrometer includes, and is powered by, a single SR44 silver oxide battery, and comes with a plastic case for storage.
Micrometers are precision measuring instruments that use a calibrated screw to measure small distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot.
Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.
