The Circ-it is a manual small diameter scanner, designed to provide encoded position of probes circumferentially around piping and tubing ranging in size from 21.4mm (0.840in) to 114.3mm (4.500in). Due to the ultra low profile design the Circ-it scanner can operate in an 11mm (0.433in) radial clearance envelope. The Circ-it is completely configurable for both dual and single probe scanning applications.
