Set of 3 Thermocouples

Set of three thermocouples for demonstrating the Seebeck effect and measuring thermoelectric voltage as a function of temperature difference from a reference point. It includes type N (NiCrSi-NiSi), type K (NiCr-NiAl) and type J (Fe-CuNi) thermocouples with 2 m leads and 4 mm safety plugs. The operating temperature range is −75 °C to 250 °C.
