Key Advantages:

5 wavelength absorption measurement: UV, Vis and IR 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.

Note：
1，TOC and BOD are calculated from COD, SS and turbidity is from SAC of Vis and IR.
2，The relationship between COD BOC SAC and TOC(from Hach)

UV254 5-beams COD Sensor with wiper

The Broadsensor UV254 sensor is an optical-based absorption and transmittance with UV LED and PD technology sensor. The sensor measures the absorption at UV 254nm, blue, green, red and IR Simultaneously to compensate the SAC measurement for interferences from turbidity and color.
