The Fowler Digital Cylinder Bore Gauge offers thermal insulation which provides extra stability. The LCD offers quick measurement reading with both inch and metric modes. This gauge utilizes a two-point contact system with three-point centering to detect geometry problems such as ovality and taper and the tungsten carbide contact tips offer high wear resistance. With switchable resolution of 0.00005"/0.001 mm and 0.0005"/0.01 mm, one gauge can cover four different display options. The gauge also has direct RS-232 output.
Bore gauges measure holes, or bores, in a workpiece. They can measure the interior diameter of a hole at any depth, while internal micrometers can only measure to the depth of their teeth. Bore gauges are typically calibrated with a setting ring and come in two types: simple and direct-measuring. Simple bore gauges are used with a caliper to transfer the hole measurement, while the more complex gauges take the measurement directly, and display it through a vernier, dial, or digital display. Bore gauges have a two- or three-point contact, indicating how many points on the gauge head touch the inside of the bore. Two-point contacts are better at measuring ovality, while three-point contacts are used to measure lobing or triangular form error. Pistol-grip bore gauges are used for fast, single-handed operation with repeatable results from one operator to another. Bore gauges can also be used in special applications, such as measuring threads, spline pitch diameters, and deep bores.
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.
