4. Thermocouple in the experiment was 2 we will use a thermometer Opto-couplers isolate it quadruple mass spectrometer-
Opto-couplers isolate it is a thermometer type T quadruple mass spectrometer, we will be used to measure temperature at the entrance and the exit of the water and air and a thermometer type Opto-couplers isolate it quadruple mass spectrometer K we will be used to measure temperature on the surface of copper (heat sink).because the area that we want to do the temperature measurement range, there is a need to vary, and the accurate value.
