Magnetic crawler
for storage tank inspections

  •  Rainproof, windproof, dustproof
  •  4 tanks 20mx20m per day
  •  A-scan + B-scan + video camera
  •  3 years warranty





ALTISCAN is a new generation magnetic crawler, developed for thickness measurement on storage tanks.

Based on a military-grade magnetic crawler, this innovative robot has been developed to reduce inspection time on storage tanks, ships, and large surfaces of steel.

With its patented magnetic system, ALTISCAN moves at 12 meters/min on vertical plates.

This rugged vertical climber also works under rain, wind, and degraded surfaces.

Its embarked electronics delivers continuous thickness measurement up to 5 measure by cm.

Thicknesses measures are saved and displayed in a simple interface in Ascan, Bscan.

Inspection report in automatically generated and displays max, min and average thickness measures by plate.

Its ultra-portable battery & electronics (4 kgs) is easy to carry in the field with a large autonomy (1 day).

It complies with API653, EEMUA 159, and CODRES procedures.


In normal conditions, 2 operators equiped with ALTISCAN can inspect 4 to 7 storage tanks by day, or 1 000 meters of linear inspection.

ALTISCAN is built, repaired and upgraded in Nantes, France.
