Máy đo độ căng bề mặt dầu tự động UHV-670 là một công cụ để kiểm tra giá trị sức căng bề mặt dầu hoặc chất lỏng. Đo sức căng bề mặt của các chất lỏng khác nhau (giao diện lỏng-khí) và sức căng bề mặt của dầu khoáng và nước (giao diện lỏng-lỏng)
Chi tiết sản phẩm Máy kiểm tra độ căng bề mặt dầu biến áp UHV-670
Product Introduction:
The Automatic Interfacial Tension Tester is designed to measure both the surface tension of liquids (at liquid-gas interfaces) and the interfacial tension between mineral oil and water (at liquid-liquid interfaces), in full compliance with the GB6541-86 standard — "Method for Determination of Oil-Water Interfacial Tension of Petroleum Products" (Ring Method).
Featuring a color touch screen display and clearly labeled Chinese menu prompts, the instrument offers a highly automated and reliable testing process with excellent repeatability. Operation is extremely simple: after powering on, all tests can be easily completed by following the intuitive on-screen menu instructions.

2. Highly Reliable Performance: Designed with advanced automation for consistent and dependable operation, delivering excellent repeatability across tests with minimal user effort.
3. Streamlined Testing Process: Simply power on the instrument and follow the on-screen prompts to complete all measurements — no complex setup or training required.
Working principle:
The working principle of the instrument is to apply the high-frequency induction micro-displacement automatic balance measurement systemto the torsion balance,that is, when the force acting on the platinum ring changes, the balance bar connected with the platinum ring is in the two eddy current probes Displacement occurs in the two eddy current probes, causing the differential transformer to lose balance, and the input signal of the differential amplifier in the circuit also loses balance. After being amplified by the amplifier, the output is amplified by the platinum ring. The electric signal that changes with the force, this signal is sent to the microprocessor for processing, and the actual tension of the tested sample is automatically calculated according to the international GB6541.
