2. KD2 Pro Overview
If measurements need to be made in concrete that has already
been cured, holes can be drilled into the sample using the pro-
cedure outlined above in the section titled “Installing the Sen-
sors.”
Measurements In Insulation
Insulation measurements are best made with the KS-1 probe
using a 10 minute read time. The long read time minimizes
contact resistance errors, and the low heat of the KS-1 needle
reduces free convection errors. In foam insulation a hole
should be drilled for the probe. Simply pushing in the needle
can cause the insulation to bunch in front of the needle tip
resulting in a poor fit and a consequently a faulty reading. In
fiber type insulation materials, assure that the insulating mate-
rials are not unduly disturbed by the needle insertion. (i.e.
pushed in front of the needle tip). Do not allow the probe to
move during the measurement.
