China Fuootech ISO ASTM Platinum Ring Automatic Liquid Interfacial Surface Tension Meter, Find details about China Tensiometer, Interfacial Tension Tester from Fuootech ISO ASTM Platinum Ring Automatic Liquid Interfacial Surface Tension Meter
FT-ZLS Automatic Interfacial Tension Test Equipment is based on platinum ring method to achieve accurate measurement of liquid surface tension, meeting with ASTM D971. It integrates many advanced technologies and is widely used in chemical, petroleum, electric power, railway, research etc.
(Platinum ring method is a traditional testing method which has been about 70 years. It is made of platinum wire with a diameter of 0.37mm to make a ring with circumference of 60mm. In the test, the platinum ring dips into the liquid surface (or interface two kinds of non mixing liquid ) by 2-3mm, and then slowly lift the platinum ring up, and there will form a film between the ring and the liquid surface. The film has a pull down force on the platinum ring, measuring the maximum force exerted on the ring in the lifting process of the entire platinum ring, and then converting it into a true surface/interface tension value.)
