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 ppb_v.

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.
