Abstract

A method is provided for calibrating a thermal conductivity sensor in a first medium A from measurements in a second medium B. The method includes maintaining the sensor at a substantially fixed temperature T1, and measuring a heat flux I B (T 1 ) from the thermal element in the second medium B. A corresponding heat flux I B (T 1 ) in the first medium A is calculated using known thermal conductivities of the first medium A and the second medium B.
