What are plasma indicators?
Plasma indicators are simple and fast test methods for the detection of successful plasma processes.
If component surfaces after plasma treatment do not demonstrate the desired properties, expensive complaints can quickly result. However, there are simple methods with which a successful plasma process can be detected, without great expenditure of time.
Why are they applied?
For process control of the following plasma processes: Cleaning - activating - etching
What types of indicators are there?
Plasma indicator (liquid)
The plasma indicator-metal compound from Diener electronic offers users of plasma systems the possibility to see at a glance whether the applied plasma treatment has successfully occurred. The indicator consists of a liquid metal compound, which decomposes in the plasma. If a drop of this originally colorless liquid is applied on the component itself or a reference sample, it will transforms during the plasma treatment into a shiny metallic coating, which provides a clear contrast for most surfaces.

Plasma indicator tags
The coated film on the label is characterized by a dark (brown) indicator point, which disappearsin the successful plasma process. If no indicator point can be seen, the cleaning - activation - etching has beensuccessfully carried out.
