UV254 Self-Cleaning Five-Wavelength COD Sensor S-COD161
SKU: WQ-00709
Available
UV254 Self-Cleaning Five-Wavelength COD Sensor. 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. Build in auto wiper sub-system prevents biofouling from taking place. Feature
