Mitutoyo 340 Series Outside Micrometers

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. The micrometer 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 frame has a baked enamel finish for protection and durability. A spindle lock helps provide secure locking of the measurement position. The unit comes with an SR44 battery, standards for zero-setting, and a fitted plastic case.

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.
