The LDS 45/50 laser sensor is used to control oil contamination. LDS 30/30 is optional for diesel and kerosene pollution control. Thus, concentrations as high as 200,000 P/ml are possible. LDS 1/1 sensor is used to monitor the sink. Sensors can operate at higher flow rates. LDS sensors are characterized by their high reproducibility and good resolution. Integrated dual plunger pumps operate independently of inlet pressure and viscosity. Amf particle counters can be used in laboratory bottles, tank systems, and pressure lines.
