PONSEL TURBIDITY turbidity sensor

The measuring principle of this sensor is based on IR infrared turbidimetry / 880 nm (ISO 7027). Calibration is performed with formazine standard solution. Integrated low-cost optical technology, less maintenance and no consumables. With Modbus RS-485 or SDI-12 signal interface can be connected to any type of transmitter, display unit, controller or data logger. All data about calibration, historical data, users and measurements are processed directly by the sensor and transmitted via RS-485 or SDI-12. It can be used for portable measurement and long-term monitoring.
