INSIZE 3509-50 Bluetooth Digital Indicating Snap Gauge, 25-50mm/1-2"

The INSIZE 3509-50 is a Bluetooth digital indicating snap gauge covering 25-50mm/1-2" with 0.0001mm/0.000005" resolution, 1μm accuracy and 0.3μm repeatability, reading out on both a digital display and an analog-style dial that turns green, yellow or red for in-tolerance, under-tolerance and over-tolerance parts. Its absolute encoder keeps the reading in memory when the unit is switched off, the anvil retracts 1mm at the press of a button to load a part, and the measuring faces are carbide. A rechargeable battery runs it for 20 hours, and built-in IP54-rated Bluetooth or a USB-C cable send readings to the INSIZE app or a spreadsheet, with gauge blocks available as a zero-setting accessory.
