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

UV 254 Double-Wave COD Sensor

The Broadsensor UV254 sensor is an optical-based absorption and transmittance with UV LED and PD technology sensor. The sensor measures the absorption at 254nm and 550nm at the same time to compensate the SAC measurement for interferences from turbidity and color.
