Jireh ROTIX – 4 Probe Weld Frame Scanner

Scan both ferrous and non-ferrous materials with a flexible four probe chain scanner.

The ROTIX – 4 Probe Weld Frame Scanner provides the encoded probe position of four probes circumferentially around tubes and pipes. Manually operated, this double wheel chain scanner straddles the weld, allowing the scanner frame to be centered on the weld, thus reducing wandering and scanner width. Adapt this chain scanner for outer diameter scan surfaces of 10.2 cm – 96.5 cm (4 in to 38 in) using multiple combinations of short and long links.

Adjustable Chain

Using two link lengths and an adjustable buckle, pipes and tubes ranging from 10.2 cm – 96.5 cm (4 in – 38 in) diameter may be scanned with ease. The quick release links are designed for simple and efficient chain setup.

Double Wheel Chain

The double wheel chain straddles the weld to allow the scanner to be centered on the weld. This alleviates scanner wandering and reduces the width of the scanner.


Prevent scanner movement when required.


Urethane wheels reduce the effects of debris effecting scanner travel in addition to eliminating slippage during vertical applications.

Spring-Loaded Encoder

The spring loaded encoder maintains encoder contact with the scan surface at all times ensuring accuracy. The encoder’s output is fully compatible with most standard instruments.

Overhead Adjustable Link

Raise the overhead adjustable link to provide space for large probes to operate. Lower the overhead adjustable link when low-profile scanning is required.

Slip Joint Probe Holders

Easily adjust probe centre spacing and probe alignment with these probe holders designed to accommodate most major phased array wedge types.


Convenient handles offer control of the scanner as well as mounting points for accessories such as cable management.

Modular Design

One tool for many scan applications. Convert the ROTIX to a magnetic STIX scanner with a conversion kit.

Component Identification


1 Overhead Adjustable Link

The overhead adjustable link adjusts to accommodate oversized probes. When low profile scanning is required, the link may be contracted.

2 Frame Bar

The kit includes a 40 cm (15.7 in) frame bar, however, various lengths of frame bars are available for various scan applications.

3 Slip Joint Probe Holders

Four slip joint probe holders carry two phased array and two TOFD wedges.

4 Handles

Handles allow a grip point for the scanner as well as a mounting point for various accessories.

5 Short Link

Multiple short links complete the chain configuration around pipes and tubes.

6 Catch Link

The catch link completes the chain connection around the scan surface. Use the dovetail mount to carry accessories when required.

7 Short Link with Dovetail

Utilize the dovetail mount to add accessories to the scanner such as cable management.

8 Long Link

Equivalent to (approx.) 3 short links, the long link is useful during large diameter scan setups.

9 Buckle

The buckle connects to the catch link to form the chain system which mounts the scanner to the inspection surface.
