- Sealless design
- Extremely low maintenance
- Recognition of the phase change by turbidity or colour
- Easy selection of the right model due to fix pathlengths
- Easy configuration and system integration
The PhaseGuard monitors interface changes of turbidity or colour. Three models of the PhaseGuard cover the possible applications: interface switching for turbidity (model T), for colour (model C), for high turbidity (model HT). The PhaseGuard is factory adjusted with a universal measuring range based on absorption. For simple applications and system integration the instrument configuration and communication can be easily done using the serial interface in combination with the existing outputs. For a more comfortable installation and operation the optional control unit SICON with touch screen technology and colour display can be connected.
