Measuring Technique
Infrared Duo scattered light technique for color-independent turbidity measurement
Turbidity in accordance with DIN EN 27027 / TS equivalent DIN 38414
Measuring Range
t-line turbidity: 0.001–4000 FNU/NTU
ts-line, inline turbidity: 0.001–4000 FNU/NTU; TSS content: 0.001 mg/L–50 g/L
hs-line, highline turbidity: 0.001–4000 FNU/NTU; TSS content: 0.001 mg/L–500 g/L TSS
Reproducibility Turbidity < 1 %, Total Suspended Solids (TSS) < 3 %
Measuring Accuracy
Turbidity up to 1000 FNU/NTU:
without calibration < 5 % of the measured value ± 0.01 FNU/NTU
with calibration < 1 % of the measured value ± 0.01 FNU/NTU
Technique variation
