The optimal choice for weld inspection on ferrous surfaces

Track welds circumferentially or longitudinally with up to 6 probes. Follow welds with the steerable, remote operated NAVIC - Weld Scanner, equipped with magnetic wheels which allow vertical and inverted weld inspection to be performed with ease. Various probe holder frames expand the weld scanning possibilities. From low-profile for restricted access to spiral welds and long seam inspection, the NAVIC is the industry leader in non-destructive testing for weld inspection.

Features

Motorized Driving and Steering

Variable drive speed and steering control.

Rugged

Designed to handle intense tasks and challenging environments (dust tight, watertight)

Magnetic Wheels

Magnetic wheels provide the foundation for scan operations on ferrous surfaces

Low Profile Design

The Navic can circumnavigate pipes as small as 7 cm (2.75 in) OD while only requiring 7 cm (2.75 in) of radial clearance when low profile scanning is required.

Remote Control

Program drive paths from up to 30 m (100 ft) away using the intuitive handheld remote control. The ergonomic handheld controller includes drive paths and system diagnostics.

Many Accessories

Enhance the NAVIC's capability with optional accessories: battery powered laser guide, onboard camera, backpack, cable management, crawler removal system and motorized couplant pump

Warranty

Engineered and designed to perform flawlessly. We back our products for 3 years.
