When scanner access is limited, the CIRC-IT makes single probe scanning possible.

Small diameter, low profile scanning, made possible with the CIRC-IT – Single Probe Weld Scanner. Designed to provide encoded probe positioning circumferentially around piping and tubing ranging in size from 21.4 – 114.3 mm (0.84 – 4.5 in), this manually operated scanner can operate in an 11 mm (0.433 in) radial clearance envelope due to the ultra low profile design.


Component Identification

Durable urethane wheels provide smooth rolling and adequate traction in vertical scanning applications.

The CIRC-IT scanner features a cable management system for irrigation lines and probe cables.

Links provide infinite adjustment for pipes or tubes to be scanned between 21.4 – 114.3 mm (0.84 – 4.5 in).

Carries Olympus A15 small-footprint probes and wedges.

The included irrigation kit contains the necessary hoses, fittings, tubing, etc, required to connect a couplant pump to the probe(s) being carried by the scanner

A spring-loaded encoder maintains constant contact with the scan surface for precise encoder measurements.
