The laser sensor LDS 45/50 is used for contamination control of oils, diesel and kerosene. For the contamination x (drinking water, fluids in the  pharmaceutical and chemical industry)  an LDS 30/30 is available as an option. Concentrations of up to 200.000 p/ml are possible then. The sensor LDS 1/1 is used for monitoring cleaning baths. The sensor can be operated with a higher flow volume. Features of the LDS sensor include high reducibility and good resolution. The  integrated double piston pump works  independent of inlet pressure and viscosity. The particle counter PCSS fluid lite can be operated out of lab bottles, tank systems and pressure pipes.
