S461 Turbidity Probes/SS submersible
The S461 sensor is used for optical turbidity and suspended solids measurement in pure and process water up to 4000 NTU or 20 gr/l. The probe uses the 90° Scattered Light Method.
Applications
• Measure in wastewater
• Measure in primary water, industrial water, recirculating water
Range: Turbidity
• 0,0÷4,00 NTU ; 0,0÷40,0 NTU ; 0÷400 NTU ; 0÷4.000 NTU
• Resolution0,01 NTU ; 1 NTU
Range: Suspended Solids
• 0÷20 gr/l
• Resolution0,1 gr/l
Avaiable versions with double parameter:
• 4263-83[Suspended Solids - Dissolved Oxygen]
• 4263-93[Suspended Solids - Chlorine]


The 7520 SAV and 7540 SRH sensors are used for optical solids content measurement in turbid water for up to 150g solid matter/l.
Applications
• Solids content measurement of suspended matter in sewage treatment plants: Primary sludge, digested sludge, thickened sludge, Inflow to centrifuge / press
• Industrial quality control
Features and benefits
• Reliable concentration measurement using optical measuring process
• Four-beam pulsed light method for compensation of sensor soiling and ageing of optical components
• Stainless steel sensor body
• No mechanically moving parts
• Measured value preprocessing in sensor resulting in low signal transmission sensitivity
