Fluid Viscosity
The portable analysers are designed to handle a fluid viscosity of up to 460 cSt for the small unit or
2400 cSt for the larger units
. It’s possible to pass high viscosity oils through the unit if they are
preheated as per the below table.
Note that as a pre-heated oil passes though the unit it will cool, therefore increasing its viscosity and
strain on the pump.

Internal Gear Pump
The internal gear pump provides a steady flow for accuracy of results. Fluids above the rated
viscosity can cause excess motor strain and cause it to overheat or slip.
It’s important to pay
attention to the grade of oil being analysed and its temperature.
