SZ518-AWater Monitoring
Self-Cleaning Sludge Concentration Sensor
This self-cleaning sludge concentration sensor measures sludge concentration from 0 to 50000 mg/L with ±5% accuracy (depending on activated sludge homogeneity) and RS-485 MODBUS output. It uses infrared scattered light and has a self-cleaning brush to reduce contamination. Suitable for activated sludge monitoring and water quality analysis in wastewater treatment.
