(Sunnen Products: St. Louis) -- Sunnen Products, manufacturer and distributor of bore sizing machines, abrasives, and engine building products, now offers large-readout electronic indicators on its entire range of dial bore gauges. Highly visible in the shop environment and a quick reference for multitasking operators, the gauges feature precision indicators with six-digit LCD readouts, 11 mm character height, and three large buttons for easy operation.

Capable of checking bore sizes from 0.054 in. (1.37 mm) to 12 in. (300 mm) and bore lengths up to 24 in. (600 mm), the gauges allow users to set upper and lower tolerance limits for go/±no go judgments, which are then displayed in full-size characters. Standard analog indicator-equipped gauges read out in tenths (0.002 mm); models with five-tenths (0.010 mm) readouts are also available. Operators can easily toggle between inches and metric measurement readouts.

The electronic indicator dial bore gauges, accurate to ±0.00012 in. (±0.003 mm) with 0.00005 in. (0.001 mm) resolution, provide the ability to perform scaling calculations, judge tolerance, hold data, and perform general comparison measurements. Internal calculations using a simple F(x) = A(x) formula are also possible.
