Oil Interfacial Surface Tension Meter Du Nouy Ring Tensiometer ASTM D971
I.Introduction
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. HZZL-3 automatic tension tester apply to GB/T6541,it can test kinds of liquid surface tension and boundary surface tesion.this method sample and accuracy,so it's used widely.
II.Function
It used electromagnetic force -balance-type transducer, improving the accuracy of the measurement
Demarcated one point and you can adjust the instrument, and it's very convenient.
The instrument can show current weight values and tesion Equivalence
The instrument can revise the test result Automatly
