Thermogenerator, Peltier element

Function and applications

For direct conversion of heat energy into electrical energy and for use as a heat pump as well as for demonstrating Seebeck and Peltier effects. 2 nickel-coated copper brackets with temperature measurement points for thermometers and temperature sensors plus 4-mm sockets. A Peltier element with 71 silicon thermoelements thermally connected in parallel.

Benefits

• Tough copper bracket
• Temperature measurements can be made directly from the copper bracket thanks to holes for thermometers or temperature sensors
• Simple electrical connection via 4-mm sockets
