1.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. automatic interfacial 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.

2.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
* Used high-quality screen,the life of screen extended
* The instrument can storage 255 records
* The instrument has a mini- printer,you can print the test result any time.
* The instrument has RS232 interface equipment,it can connect to computer,and it convenient for data processing.
