4 arm geotechnical bored pile caliper and inclination tester
Summary
4 Arm Geotechnical Bored Pile Caliper and Inclination Tester Pile Caliper Logging Test Equipment
The Caliper Log is a tool for measuring the diameter and shape of a borehole. It uses a tool which has 2, 4, or more extendable arms. The arms can move in and out as the tool is withdrawn from the borehole, and the movement is converted into an electrical signal by a potentiometer
