5E50.10 - Thermocouples
Show different thermocouples.
InstructionsThere are several thermocouples available. One is a set of four thermocouples on an asbestos board with banana plug connections. Connect a zero center projection galvanometer across the terminals and heat the outer edge in a Bunsen burner. Do not overheat. It should be possible to get a deflection in the other direction by cooling the same junction with dry ice or liquid air.
