Overview


 The Multi-Finger Imaging Tool (4-finger) has been designed to provide the most accurate pipe caliper measurements in the industry, and the high quality data allows for 3 dimensional imaging, calculation of corrosion rates or scale deposition. There are an inclino sensor and a rotation sensor built in for caliper reading correction.

Application

· Corrosion assessment
· Deformation evaluation
· Perforation measurement
