The laser sensor LDS 45/50 is used for contamination control of oils. An LDS 30/30 can be used optionally for the contamina-tion control of diesel and kerosine.  Concentrations of up to 200,000 p/ml are possible with it. For the monitoring of cleaning baths the sensor LDS 1/1 is used. The sensor can be operated with a higher flow rate. The LDS sensor features a high reproducibility rate and good resolution. The integrated double piston pump works independently from the input pressure and viscosity. The particle counter Amf can work from lab bottles, from tank  systems and from pressure lines.
