The model GA65 measuring instrument has been specifically designed for measuring small concentrations of SF6 gas. The quantitative measurement of SF6 gas in the air is carried out reliably and reproducibly even at the smallest quantities.
The used technology is based on the photo-acoustic infrared spectroscopy. This physical and non-destructive measuring principle achieves a very high accuracy with a detection rate of 6 ppbv.
Humidity is compensated and thus does not influence the measuring result.
Cyclic self tests guarantee the reliability and functionality of the instrument. It is recommended to recalibrate the instrument once a year.
The leak rate measuring instrument is easy to use and can be operated via control keys at the front of the housing or via an extensive PC software with a graphic user interface.
Both operating modes allow for the setting of the parameters (e.g. duration of the sampling), the starting of a measurement (manually or automatically), the display of the concentration of SF6 gas in real time or the sending of the values to the downstream control software.
