Fowler 52-611-011 EZ-Read Digit Tube Micrometer, 0-1" Measuring Range, 0.0001" Graduation Interval, 0.0003" Accuracy

The Fowler 52-611-011 EZ-Read tube micrometer has a 0 to 1" measuring range to measure the wall thickness of tubing. The digit scale has 0.0001" graduations and an accuracy of 0.0003" for precise readings and accurate measurements. Carbide-tipped anvils provide wear resistance and are fitted with an adjusting collar to set the overall dimension. The spindle thread is hardened, ground, and micro-lapped to provide smooth movement, accuracy, and long life. The positive locking lever on the spindle locks measurements in place for accurate readings. A friction thimble provides smooth and quiet operations, and is suitable for one-handed operation. Friction-style thimbles stop turning when the spindle comes into contact with the workpiece, providing constant force for consistent measurements between operators. The heat-insulated steel frame helps reduce temperature-related expansion or contraction providing accurate measurements. The micrometer includes a fitted case.

Micrometers are precision measuring instruments that use a calibrated screw to measure 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.

The Fred V. Fowler Company manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA.
