Surface tension is one of the most important indicators of oil quality, reflecting contamination, degradation, and stability. Using an electromagnetic force-balance transducer, the HZZL-3 ensures highly accurate and repeatable measurements. With a user-friendly design, historical data storage, and convenient calibration process, it provides laboratories and field engineers with a precise and easy-to-use testing solution. The HZZL-3 supports both online and offline printing, enabling fast report generation. Test data can be stored internally or exported to a computer for further processing and analysis. Compact in design yet robust in performance, it operates reliably in laboratory conditions with stable power consumption. The HZZL-3 is widely used in power utilities, transformer maintenance, petrochemical industries, and research institutions, where monitoring oil quality and surface tension is critical to ensuring safe and efficient operation of electrical equipment.
