The most advanced Langmuir Probe on the market

How do you check if your plasma process is the same each time?

- Measure your plasma parameters!

The Langmuir Probe is one of the most common and widely used plasma diagnostics. It can be used in many different plasma applications up to atmospheric pressures. By measuring plasma parameters, models can be verified and processes can be optimised to ensure stability.


With a Single Langmuir Probe you can measure:

Current Voltage IV characteristic of a single Langmuir probe

• Floating Potential

• Plasma Potential*

• Plasma Density*

• Ion Current Density

• Electron Temperature (Te)*

• Electron Energy Distribution Function (EEDF)

* Double probe parameters measured
