t-line: 0.001–4000 FNU/NTU
High-resolution turbidity probe made of plastic for the outlets of sewage treatment plants
and bodies of water.
ts-line: 0.001–4000 FNU/NTU; 0.001 mg/L–50.0 g/L
High-precision turbidity and solids probe made of stainless steel or plastic for
color-independent measurement of fine turbidities and sludges.
hs-line: 0.001–4000 FNU/NTU; 0.001 mg/L–500.0 g/L
High-precision turbidity and solids probe made of stainless steel or plastic for
color-independent measurement of highly concentrated sludges.
inline: 0.001–4000 FNU/NTU; 0.001 mg/L–50.0 g/L
High-precision pipe installation probe for turbidity and solids made of stainless steel for
color-independent measurement of fine turbidities and sludges.
highline: 0.001–4000 FNU/NTU; 0.001 mg/L–500.0 g/L
High-precision pipe installation probe for turbidity and suspended solids made of stainless
steel for color-independent measurement of highly concentrated sludges.
The measuring principle is based on a combined infrared absorption scattered light
technique that measures the lowest turbidity values in accordance with DIN EN 27027 just
as precisely and continuously as high sludge content. Using this method, the light
scattered sideways by the turbidity particles is measured over an angle of 90°.
The sensor contains high-quality optical and electronic assemblies. Make sure the sensor
is not subjected to any hard mechanical knocks. There are no customer-serviceable items
inside the sensor.
