What is Three-Arm Caliper Probe Specifications about?

This document describes a three-arm caliper probe used for borehole logging. It has three mechanically coupled arms that are extended into contact with the borehole wall to continuously log the diameter. It comes in 38mm and 60mm models to suit different borehole diameters. The caliper provides a simple first log to determine borehole conditions before running other probes. It can also measure natural gamma levels and be used to calculate borehole volume and identify lithology, fractures, and casing problem
