Mount Sopris - Model QL40-CAL - 3-Arm Caliper Probe Records
The QL40-CAL Caliper probe records a single continuous borehole diameter log by means of three mechanically coupled arms in contact with the borehole wall. The 3 arm caliper measurement is a useful first log to determine the borehole condition before running other well logging probes.
