Have anyone any information about conductivity sensors?
(Especialy with 4-20 mА current output and relay output)
With supplier and model no. Please.

I need conductivity and turbidity sensors for UF system (Ultra Filter) in automobile paintshop.
The range of conductivity sensor is 0~2000 Micro Siemens.
and range of turbidity sensor is 0~4 CU.
