Athol, Massachusetts – The L.S. Starrett Co. has introduced two new Bluetooth enabled series of electronic digital bore gages with a range of accuracy and convenience features for increasing measurement throughput when inspecting internal hole dimensions.

781BXT AccuBore Electronic Bore Gages are a trigger-activated, two-point and three-point bore gaging system with extended range. Single-hand operation provides increased measurement speed, control, and throughput. A user simply squeezes the trigger, inserts the gage into the bore and releases the trigger, producing an instant reading from a large, easy-to-read digital display.  Speed and convenience is further enhanced by a repositionable indicator for left, right hand, or vertical viewing and Go/No-Go tolerance indicator lights quickly display when a bore is within a preset measurement range.

Mechanically driven parallel anvils extend simultaneously, establishing true alignment to the axis of the bore, providing consistent pressure and improved accuracy compared to spring-driven contacts which are subject to pressure variations.

770BXT Bore Gages offer extended travel, reducing the need to exchange anvils, providing a wide measurement range. A precision ratchet stop provides correct contact pressure for accurate readings on the large easy-to-read LCD digital display.

In addition to Bluetooth capability, the 770BXT Electronic Internal micrometers feature IP67 level of protection against coolant, water, dirt, and dust in hostile shop conditions for measuring holes in work that is in-process on a machine.

Both bore gage series feature enhanced wear life due to carbide-faced measuring contacts that are available on sizes above 0.5" (12.5mm), resolution of 0.00005" (0.001mm), and accuracy of up to 0.00015" (0.004mm). Gages also feature push button inch/metric conversion. Wireless output capability for SPC analysis is available via USB to a PC or RS232 connection.

Bluetooth wireless technology in both bore gage series enables fast, robust measurement data acquisition capabilities without the encumbrances and limitations of cables. Wireless technology also provides a platform for manufacturers bracing to meet the comprehensive big data requirements of Industry 4.0.
