SZ510-B/SZ511-AWater Monitoring
Online Turbidity Sensor
Online turbidity sensor measures turbidity from 0.1 to 1000 NTU or 0.1 to 4000 NTU, with accuracy of ±5% or 0.3 NTU and RS-485 Modbus output. It uses the 90° scattered light method and is suited for continuous online water quality monitoring. The sensor supports zero-point, one-point or two-point calibration, and optional self-cleaning brush helps extend maintenance intervals.
