Density

Density


OELCHECK Test equipment:	Density Measuring Instrument DMA 4500 (Paar) with sample changer
Sample quantitiy needed:	15 ml
Unit:	kg/m³
Test result:	Density at 15 °C
Operating time:	~ 5 min
Analysis of:	Bio oils, fuels and oils for which the dynamic viscosity is converted into the kinematic viscosity
Brief description:	To determine the density the liquid sample is sucked into a tempered U-tube. After the filling an oscillation is activated. There is a change of the oscillation frequency between the empty and the filled U-tube. Due to this change which goes along proportionally to the density, the density can be calculated related to a temperature of 15° C.
Statement:	The density indicates for example a mixture between bio oil and mineral oil. With the density the dynamic viscosity can be converted into the kinematic viscosity or the volume can be measured if the weight is known.
