Nephelometric Turbidity Sensor, NTU
The Nephelometric Turbidity Sensor, NTU uses measurement principle of IR nephelometry/880 nm (ISO 7027). The sensor can be calibrated with a formazine standard solution. It integrates a low-cost optical technology, with a little maintenance and no consumables. The NTU can be connected to any type of transmitters, display unit, controller or data logger with Modbus RS-485 or SDI-12 inputs. Used in urban wastewater treatment (inlet/outlet controls), sanitation networks, industrial effluent treatment, etc.
IR optical sensor with optical fiber; Range: 0 to 4000 NTU or 0-4500 mg/L; Robust and waterproof (IP68); Ultra low-power consumption; Digital output Modbus RS-485; ISO 7027 compliance (Nephelometry)
Integrated transmitter: All data concerning calibration, history, users and measures are directly treated within the NTU sensor and transmitted via RS-485 or SDI-12; Handheld or fixed unit application; Measure ranges: 0 - 4500 NTU in 5 ranges; Resolution: 0.01 to 1 NTU - mg/L; Accuracy: < 5% of the reading; Working temp 0°C to + 50°C; Signal interface: Modbus RS-485 (standard) and SDI-12 (option)
