\begin{itemize}
\item A small, conductive component in direct contact with plasma.
\item The measurement output is determined: i) shape: Langmuir probe, ball-pen probe, tunnel probe, Katsumoto probe, Mach probe ... ii) by the applied voltage.
\item Measurement only at the edge of the plasma.
\item Measured quantities: plasma potential, electron temperature and density, electric fields, electron distribution functions ...
\end{itemize}
