Key Advantages:
• 2 wavelength absorption measurement: 254nm and 550nm for turbidity and color compensation.
• SAC measurement used to determine organic loading without reagents.
• Measurement directly in the process, no sample processing or reagent required.
• Fast response, minimum 10 second.
• Cold light source (UV LED) and rugged PD, long life time and low drift.
• Support leakage alarm
• Build in auto wiper sub-system prevents biofouling from taking place.
