ABM-90 / DR-4 with centralizers

Covers the largest pipe ID range thanks to exchangeable centralizers

The ABM-90 and DR-4 mapping systems are the most versatile probes in the range. Fitted with exchangeable centralizers ducts and pipes  with an ID range of 90mm to 1000mm (3.5” to 40”) can be mapped efficiently.

Physically identical to the DR-4, the ABM-90 is equipped with MEMS technology and is suitable to map 300m (1000”) lengths between waypoints. The DR-2 is equipped with Fibre Optic Gyro technology and can map unlimited lengths with a recommended waypoint spacing of 1500m (5000’).
