Product Description


HOPU ZL Series automatic tension tester apply to GB/T6541 Standard Test  ASTM D971 ,it can test kinds of liquid surface tension and boundary surface tension.Based on ring method (platinum ring method), the surface tension (liquid gas interface) and interfacial tension (liquid liquid interface) of various liquids are measured. This method has the advantages of simple operation and high accuracy and is widely used. It is widely used in power, petroleum, chemical, pharmaceutical, food, teaching and other industries.

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.


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 tension Equivalence
The instrument can revise the test result Automatic
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.

Main technical features 

The instrument adopts large LCD screen and blank button, so it is automatic, reliable, and simple and with good repeat ability. Turn on the instrument and operate the instrument as per the prompt of menu, and you can complete the test as per the prompt.
