+86 15898932201The Online COD Turbidity Sensor FT-S1S, manufactured by Fengtu Technology, utilizes the UV254 absorption method and dual light source measurement technology to determine the COD value by measuring the absorption of ultraviolet light by organic matter dissolved in water. It also automatically compensates for turbidity and collects temperature data for temperature compensation.
Technical Specifications:
Measurement Principle: UV254 absorption method; dual light source measurement.
COD Range: Default 0～500mg/L, customizable to 0～200mg/L.
Resolution: 0.1mg/L.
Accuracy: ±5%, ±0.3℃.
Turbidity Range: Default 0-400NTU, customizable to 0-200NTU.
Resolution: 0.1NTU.
Temperature Compensation: Automatic temperature compensation.
Output Method: RS-485 (Modbus/RTU).
Storage Temperature: -5-+65℃.
Operating Environment: 0～50℃, ≤0.2MPa.
Installation Method: Immersion installation, 3/4NPT installation threads.
Cable Length: 5m.
Power Supply: DC: 12V-24V.
Protection Rating: IP68.
Calibration Method: Two-point calibration.
Housing Material: 316L stainless steel.
The sensor wiring is a 5-core shielded cable, including a red power wire, black ground wire, green 485A wire, and white 485B wire. When installing, it is important not to invert the sensor and to install it at an angle of at least 15 degrees or more.
The sensor is pre-calibrated at the factory, and general user calibration is not required. If user calibration is performed, the factory calibration can be restored by executing the restore to factory command.
