Thermal Testing of Building Insulation Materials
... This is done by fixing the desired test specimen as a border between a hot chamber and a cold chamber as shown in Figure 1. The hot and cold temperatures are held constant and are recorded. From this the heat transfer through the material can be found and, in turn, a U-value or an overall thermal re ...

... In this last figure we get a better idea of how this instrument can function as either a conductivity meter or an ion counter and how it transitions from one to the other. For a given rate of air flow through the cylindrical capacitor we monitor the signal current as the potential difference betwee ...
