◼ IR optical sensor with optical fibre ◼ Range : 0 to 4000 NTU or 0-4500 mg/L ◼ Robust and waterproof (IP68) ◼ Ultra low-power consumption ◼ Digital output Modbus RS-485 ◼ Nephelometry measurement

Application : ◼ Urban wastewater treatment (inlet/ outlet controls) ◼ Sanitation network ◼ Industrial effluent treatment ◼ Surface water monitoring ◼ Drinking water Optical technology : The measure principle is based on IR nephelometry / 850 nm. The sensor can be calibrated with a formazine standard solution. The NTU sensor integrates a low-cost optical technology, with a very few maintenance and no consumables
