-Semiautomatic Tensiomat performs ASTM D 971-99a (oil-water interfacial tension procedures) and D 1331-89 (methods for measuring surface and interfacial tension of detergents)
-Employs du Noüy ring method for direct results with no calculations
-Accuracy equals data from capillary-height or drop-weight measurements to within ±0.25%
-Measures force necessary to separate platinum-iridium ring from liquid, read directly to ±0.25 dynes/cm
-For comparative studies, data is easily convertible to absolute values using graph in supplied instructions
-Reversible motor for improved accuracy compared to manual tensiometers
