Viscosity is a critical indicator for evaluating the performance of lubricating oils. The kinematic viscosity of oil is an essential basis for determining the lubrication status of equipment and deciding whether an oil change is required. During use, lubricating oils may experience viscosity reduction due to contamination, degradation, and other factors. If the viscosity change exceeds the allowable range for equipment lubrication, it can lead to poor lubrication and abnormal wear. Therefore, monitoring the kinematic viscosity of oil is crucial in routine oil analysis.
The HFN-B Portable Viscometer measures the kinematic viscosity of oil at 40°C using the capillary method, enabling users to quickly and accurately assess changes in oil viscosity. This helps improve equipment reliability and avoid losses caused by unplanned downtime. The instrument allows users to customize the viscosity index and automatically calculates the kinematic viscosity at 100°C based on the viscosity index and the measured viscosity at 40°C. Equipped with multi-point calibration, the HFN-B ensures high detection accuracy.
