3 different methods used: 

- Mini contact: determines potassium bitartrate (KHT) precipitation expressed in µSiemens. This value indicates the stability of the wine being tested
- Saturation point: automatically, the analysis provides the saturation temperature expressed in °C of the test sample.
- Mini contact with Forecast method determines KHT precipitation expressed in μSiemens. By using CheckFuture®, it predicts precipitation of crystals.
Once the instrument has been prepared for an analysis, it will proceed automatically requiring no further intervention by the operator until the last step (final washing of probe assembly).
