Enjoy the versatility of the MICROBE – 4 Probe Weld Scanner with features that include: an integrated encoder that tracks positional movement. An ergonomic handle for comfort and control. A brake that maintains a scanner position when required. Additional magnetic wheels offer an increase of magnetic attraction to the scan surface. The combination of these features all adds up to a superior manual magnetic scanner experience.

This product does not have additional information.

Modular Design

The MICROBE scans on non-ferrous surfaces with a ROTIX conversion kit. The MICROBE can augment a ROTIX system.


The removable MICROBE umbilical is the transmission point of the positional encoded signals to a user’s instrument. Plug-in optional accessories for two-axis scans as well.

Brake System

A brake is provided to lock the location of the scanner in a required position.

Magnetic Wheels

The magnetic wheels are coated with urethane to reduce the effects of foreign debris obstructing scanner motion. Dual magnetic wheels add to the magnetic attraction.

Removable handle

The MICROBE has a removable handle allowing easy access to protected connections as well as providing cable management.

Built-in Encoder

Integrated encoder maintains a meticulous record of travel. The encoder output is fully compatible with all standard instruments.

Probe Holders

The extremely adjustable slip joint probe holders accommodate most major types of phased array and TOFD wedges. Perform simultaneous TOFD (time-of-flight diffraction) and Phased Array scans

Component Identification


1 Cart

The MICROBE Cart contains the built-in positional encoder while the removable handle allows for cable management and access to the umbilical.

2 Frame Bar

Various lengths of frame bars, to which the probe holders and accessories mount, are available.

3 Phased Array Slip Joint Probe Holders

The versatile slip joint probe holder carries the phased array wedge with seemingly endless adjustment possibilities.

4 Magnetic Wheels

The magnetic wheels maintain scanner contact with the inspection surface. Add additional magnetic wheels to double the magnetic attraction.

5 Brake

A brake prevents the MICROBE from unwanted rolling on a scan surface.

6 Umbilical

A vital component to the MICROBE, the umbilical housing is a plug-in for optional y-axis accessories. As well, the umbilical exports encoder signals to the user’s instrument and acts as a means of cable management.

7 TOFD Slip Joint Probe Holders

Mount TOFD wedges to the slip joint probe holders.
