Intermolecular Forces formed liquid surface tension. Numbers of tension reflect on liquid sample’s physics and chemical properties; it is one of the most important index to product quality.
Series FT-ZL Automatic Interfacial Tension Tester uses the ring method (GB 6541-86 & ASTM D971) under non-equilibrium conditions to test liquid surface tension (liquid- vapor interface) and mineral oil and water interfacial tension (liquid-liquid interface).
Series FT-ZL uses a microprocessor technology with large-screen color LCD Display and automatic printing test results, with high automation and interactive ability. This tester is the new generation product in many industries such as power plant, petroleum, chemical, pharmaceutical, food, teaching and other industries.
