The IPC Thermopile (IPC-4652-W) uses a multijunction thermopile housed in a transistor type package, this element along with its amplifier are housed in a 140mm rod with a 400mm cable terminated with red, black and white 4mm connection plugs. By using a sensitive digital voltmeter capable of reading millivolts to volts (we recommend the IPC 2VDC Digital Voltmeter IPC-1904-M) the differing radiant energies from the surface of a Leslie cube can be demonstrated.
To operate the Thermopile a DC supply voltage of between 7V to 25V is required and for this we recommend using the IPC Student Power Supply IPC-0256-P (located within our IPC Power Supplies section). A full set of instructions are supplied with the Thermopile and further operating and experiment advice can be obtained by contacting IPC directly.
