The ROTIX – 3-Axis Nozzle Scanner facilitates semi-automated inspection of nozzle welds. A specialized long-stroke probe holder features encoded skew angle measurement, while the scanner employs a chain system for stable inspection on both ferrous and non-ferrous surfaces. The scanner is also capable of limited clearance inspection, requiring just 12.7 cm (5.0 in) between the vessel and flange.

This product does not have additional information.

Adjustable Chain

Configure chain links to scan diameters of 7.6 cm – 60 cm (3 in – 24 in) with our exclusive chain design.

Slider Probe Positioning System

Make quick adjustment to the probe distance from the weld without requiring scanner removal. The included encoder ensures precise measurement along the frame bar.

Y-Axis Encoding

Measure probe distance from the weld.

ROTIX Low Profile Link

In addition to containing the scanner’s positional encoder, the low profile link transmits all three encoder signals to the user’s instrument. Utilize the low profile link’s dovetail grooves to organize cables and tubes.


 Prevent scanner movement by applying the brake.


Encoded Skew Vertical Probe Holder

This inventive probe holder offers 12.2 cm (4.8 in) of vertical travel as well as an encoded skew measurement.


Urethane wheels offer smooth scanner motion while travelling around a scanned object.

Cable Management

Cable clips mount to various locations on the scanner, probe holder and frame bar. These simple clips facilitate cable management on the equipment, while protective sleeving organizes and protects cables and hoses to the user’s instrument and irrigation solution.


A three-year limited warranty backs all products. Contact JIREH for more information.

Component Identification


1 Catch Link

The attachment link for the buckle which completes the chain system.

2 Short Link with Dovetail

The addition of the dovetail allows for the mounting of accessories such as the cable management.

3 Short Link

Connect the required amount of short links to form the chain length required for various pipe and tube diameters.

4 ROTIX Low Profile Link

The low profile link contains the system’s positional encoder as well as cable management mounts, the brake, connection point for the frame bar and inputs for additional encoder signals. The encoder output is compatible with most industry-standard instruments.

5 Long Link

Roughly equivalent to 3 short links, the long link is useful during large diameter scans.

6 Buckle

The buckle fastens to the catch link and allows control of chain tension.

7 Skew Encoder

Probe skew angle is recorded using the skew encoder.

8 Long Stroke Probe Holder

The long stroke vertical probe holder offers immense travel over various scan surfaces.

9 Slider PPS

Position the probe holder closer or farther from the weld with ease.

10 Slider PPS Encoder

Offset position is recorded using the slider PPS encoder.
