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.
The ABM-90, short for “As-Built Maker-90”, is equipped with MEMS technology and is suitable to map 300m (1000”) lengths between waypoints.
The DR-4, short for “DuctRunner™-4″, equipped with Fiber Optic Gyro technology and can map unlimited lengths with a recommended waypoint spacing of 1500m (5000’).
