1. particle concentration (from which     cleanliness classes based on several     standards are derived)
2. oil temperature
3. oil viscosity

1. analysis from bottle samples
2. online measurement at the pressure     of the hydraulic system up to 420 bar     or 6000 psi
3. online measurements in with ecoline     ump 045 by argo ecotec e.g. during     filling or off-line filtration of a hydraulic     system for stationary or mobile     hydraulic equipment

Filtroil provides the best particle counter on the market, the PODS (portable oil diagnostic system). The unit can test particle counts ranging from 1 to 100 micron with on-line sampling or bottle sampling. The unit is portable with a protective case and can provide output in ISO MTD, ACF or NAS standards. Laser particle counting is the best way to know whether your fluids are clean enough for your equipments demands.

The heart of PODS is a new sensor for particle counting. Based on the concept of Light Extinction, it detects particles of >2µm (c) ISO-MTD (Medium Test Dust). The pressure of the hydraulic system moves the oil sample through the sensor during online operation. In bottle sampling mode, the necessary pressure to induce sample flow is produced by CO2 stored in a small refillable pressure bottle (in the field) or compressed are (in the lab). Other sensors measure oil temperature and viscosity. The sample flow rate is measured and automatically regulated depending on oil viscosity. Each sample has one run for flushing (programmable) and three measurement runs of either 5, 10 or 20 mL. The analysis time depends on the oil viscosity and is as fast as 1 minute up to 2.5 minutes.
