| OELCHECK test instrument: | Anton Paar density meter DMA 5000 |
| Sample volume: | approx. 15 ml |
| Unit: | kg/m³ |
| Values determined: | Density at different test temperatures Temperature range +10°C to +90°C at intervals of 10°C |
| Investigation for: | Lubricating oils and hydraulic fluids |
| Brief description: | The sample fluid is drawn into a tempered U-tube to determine its density. After filling, oscillation is initiated. The change in the vibration frequency of the empty and and filled U-tube, which is proportional to the density, can be used to calculate the density. |
| Conclusion: | The density temperature profile is the basis of many fluid mechanics and thermodynamic calculations. It is often used in conjunction with the viscosity temperature profile to determine the temperature profile of kinematic viscosity. |
