1.1.Turbidity/TSS/MLSS sensor
The sensor is based on the combined infrared absorption and scattering
light method, and the ISO7027 method can be used to accurately determine
the turbidity, TSS and MLSS. The main parameters of the sensor showed as
table 2:
Table 2 the main parameters of the Turbidity/TSS/MLSS sensor
Dimension
60mm*256mm (D*L)
Weight
1.65KG
Material
Body: S PVC, Ti alloy (For seawater)
O-ring: Fluorine rubber
Cable: PVC
Ingress protection
IP68/NEMA6P
Measure range
Turbidity: 0.00 ~ 4000NTU
MLSS/TSS : 0.1 ~ 20000 mg/L, 0.1 ~ 45000 mg/L,
0.1 ~ 120000 mg/L
Accuracy
Turbidity: Less than ±2% of the measured value or
±0.1NTU, whichever is larger
MLSS/TSS: less than ±5% of the measured value
(depending on the homogeneity of the MLSS/TSS)
