The WA500 turbidity si typically determined using 90 degree scattered light principle in compliance with EN ISO 7027 / EN 27027. The measured scattered light signals are converted to frequency signals and then this frequency signals are assigned to corresponding turbidity units and solid matter concentrations. The S7T1 sensor is used for the optical measurement of turbidity in pure and process water up to 4000 NTU or to determine the concentration of sludge up to 20g/l.

ㆍHigh Level of Reliability of The Measurement Thanks to The Use of Optical Infrared Technology (880nm) 
ㆍ90° Scattering Method for Turbidity and Absorption (according to Beer-Lambert) for Suspended Solids
ㆍStainless Steel 316 Sensor Body
ㆍNo Moving Mechanical Parts
ㆍMeasurement Pre-processed in The Sensor Which Provides High Sensitivity in Low-signal Transmission
