High Frequency Spark Testers
Knowing what is inside a sealed vessel is a requirement in many industries, where goods are packedunder partial vacuum, for example in the pharmaceutical industry or a defined internal gas filling isneeded, for example in lighting industry or solar heatproducts. Standard spot check procedures areoften based on destroying the test samples in order to analyze the contents.
The pharmaceutical industry preserves and stores freeze-dried contents in glass containers (vials).The lighting industry uses noble gases in the inner and outer flasks of discharge lamps. In case ofsolar thermal tubes, the vacuum has to be as complete as possible and the absence of foreign gasesis required. The cosmetics industry uses airtight sealed jewellery packs, such as flacons.
For a 100% test, a solution is needed which allows the determination of the filling pressure and / orthe gas composition without destroying the sample.
By early detection of failures or tolerance overshoots, further processing costs can be effectivelysaved.
Cracks in the glass, glass breaks or leaks of the seal, which are not visible to the human eye, can leadto a slow loss of the internal pressure. This occurs during storage or transport. A quick test ofoutgoing goods or directly at the place of use provides increased safety.
