In-Line Turbidimeter for hazardous areas
The DualScat monitors turbidity in liquids, using a single light source to detect transmittel light and scattered light at 90° and 25°. This allows for getting information about the particle size causing the turbidity as well as for compensation of colour and fouling influence. Calibration check is performed with a calibration unit with a glass reference. The Ex version is offered with flameproof encapsulation for installations in areas requiring explosion protection.
