In-Line Turbidimeter

The TurBiScat monitors turbidity in liquids, optional also the (beer)colour in EBC. The combination of Hastelloy and sapphire in a sealless design allows operating the unit in practically all process applications. Turbidity measurement is done with colour compensation. Window fouling is monitored, compensated and can be checked using an anti-fouling control. Calibration is easily done using a secondary reference standard.
