Irving Langmuir(/ˈlæŋmjʊər/; January 31,
1881- August 16, 1957) was an American chemist and physicist.
On the day of his death, he received an honorary
degree from Berkeley and then met his longtime rival, Irving Langmuir,(1932 Nobel Prize winner) for lunch.
Other important devices for measuring temperature include: Thermocouples Thermistors Resistance temperature detector(RTD)
Pyrometer Langmuir probes(for electron temperature of a plasma)
Infrared Other thermometers One must be careful when measuring temperature to ensure that the measuring instrument(thermometer, thermocouple, etc.) is really the same temperature as the material that is being measured.
