Atmospheric pressure Langmuir probe
We have successfully developed the world's first Langmuir probe that can be used at atmospheric pressure.
- This is the world's first Langmuir probe capable of measuring parameters of atmospheric pressure, such as plasma torches and arc plasma, as well as thermal plasma. - It can be used at high temperatures due to the cooling water system. - Measurements can be taken with a step time resolution of 12.5 ns. (As of November 2012, the fastest in the world according to our research) - The sampling rate is 80 MSPS (V, I), making it the fastest in the world. (As of November 2012, the fastest in the world according to our research) - The automatic linear drive system allows the probe to be moved to the plasma with a step resolution of 0.025 mm, enabling spatial distribution analysis. - Equipped with an effective automatic probe tip cleaning mechanism for deposition gases. The replacement of the probe tip is also easy. - The size of the probe shaft can be customized.
