UHV-670 Automatic Surface Tension Tester-Catalog

Product catalog summary

Product Introduction
The UHV-670 Automatic Surface Tension Tester by Wuhan UHV Power Technology Co., Ltd. is designed to measure the surface tension of various liquids and the interface tension between mineral oil and water. It adheres to the GB6541-86 standard for petroleum products. The device features a color touch screen display with an English menu, offering high automation, reliability, and ease of use.

Working Principle
The instrument utilizes a high-frequency induction micro-displacement automatic balance measurement system. Changes in force on the platinum ring cause displacement in eddy current probes, leading to an imbalance in the differential transformer. This imbalance is processed by a microprocessor to calculate the actual tension of the sample according to the GB6541 standard.
