The ALP System™ is a high resolution and high performance Langmuir Probe system which can be used to characterize many plasma types including DC, pulsed DC, microwave and RF plasmas.

The Impedans Advanced Langmuir Probe (ALP) System provides a powerful diagnostic for measuring key plasma parameters in low and medium pressure discharges.

High Resolution Plasma Characterisation is possible with the state-of-the-art Langmuir Probe and ALP Control Unit electronics. Using an intelligent pre-scan feature, the optimal plasma parameter measurements can be performed easily and repeatedly.


The Impedans ALP System can provide the following primary plasma parameters in real-time:

Plasma Potential
Plasma Density
Electron Temperature
Ion current Density
