Functional description
The OPCom Portable Oil Lab is a mobile oil laboratory for service, with which oil cleanliness and oil condition in hydraulic and
lubricating systems can be examined.
The OPCom Portable Oil Lab enables measuring of particles to the latest standards and indicates the cleanliness classes in accordance
with ISO 4406:1999 and SAE AS4059.
Additionally it displays the relative humidity and oil temperature. Optionally, further information about the oil condition
can be obtained from the conductivity and permittivity of the oil and shown on the integrated display.
The OPCom Portable Oil Lab is an optical particle monitor that works according to the principle of light absorbance. The use of the
OPCom Portable Oil Lab allows the monitoring of contaminant levels as well as the observance of the trend
of changes in fluid cleanliness. With this, in the most precise cases, differences can occur compared to particle monitors that
are calibrated to ISO 11171:99. The discrepancy is, however, smaller than an ordinal number. Variances are very precisely
indicated.
Through continual monitoring of fluid conditions, changes in the machine can be detected very quickly. With quick
warning, measures can be taken to prevent increased contamination, which can lead to possible damage to the hydraulic
system.

Measured values
The following values are determined during a measurement:
Parameter
Abbre-
viation
Unit
Description
Temperature coefficient
T
°C / °F
Fluid temperature
rel. permittivity (rel. DK)
P
The relative permittivity is a parameter for the polarity of the fluid. Oils
change their polarity during the aging process.
Conductivity
C
pS/m
Fresh oils show a characteristic conductivity. Oil change, oil mixtures and
oil deposits can be detected by their conductivity.
