The temp. change of the resistor 13 is measured according to this change. In other words, when the thermal conductivity of the sample 10 is large, temp. rise of the resistor 13b is small. When the thermal conductivity thereof is small, temp. rise of the resistor 13b is large. Therefore the thermal conductivity of the sample 10 is obtained by measuring this temp. change.

A system source control part 2 first decides it from an input signal (b) forming an L level whether press of a switch SW1 is effected and secondly decides it from a signal (a) forming an L level whether the main switch SW1 is pressed. A power source is controlled on that particular time when both the signals (a) and (b) are an L level. Further, when abnormality occurs in a signal processing part 4, the signal a always produces an H level. When the signal wire W is disconnected, a signal equivalent to a cancel switch S4 is inputted to the ECU 1, thereby ensuring safety of a device.
