Product Description
ZWZL300 astm d971 surface tension meter digital tensiometer
General
Automatic interfacial tension tester, in accordance with GB6541-86 "Petroleum products oil to water interfacial tension measurement method" (circle method) standard requirements, measure the surface tension of various liquids (liquid-gas interface) and the interface between mineral oil and water Tension (liquid-liquid interface). The instrument adopts a color touch screen display and a non-marked button with full Chinese character menu prompts. It has a high degree of automation, reliable work, good repeatability, and extremely simple operation. All tests can be completed by simply pressing the menu prompts after turning on the machine.
Features
1. Color LCD touch screen
2. Sample cup
3. Ring frame rod
4. Platinum ring: for measuring sample

Working Principle
Working Principle
The working principle of the instrument is to apply the high-frequency induction micro-displacement automatic balance measurement system to 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 interna tional GB6541.
