Before you order

  • Insize ranges are listed in inch and metric; most digital tools switch between the two.
  • ISO 17025 calibration certificates are available as separate part numbers on the 1108 digital calipers, 1311 dial calipers and 2307 dial indicators (CAL suffix), and on request for those series. Gage blocks, thread gages, setting rings and other standards list a manufacturer inspection certificate where Insize supplies one.
  • Wireless (WL) tools need a receiver; data-output tools need the matching cable. Both are under Data Collection & Wireless.
