Product Description

ASTM D971 Tensiometer Interfacial Tension Tester with Ring Method Test Equipment

Product Description

GD-6541A ASTM D971 Oil-Water Interfacial Tension Tester is designed ASTM D971 "Standard Test Method for Oil-Water Interfacial Tension by Ring Method". The surface tension tester is used to determine the interfacial pressure between mineral oil and water in a non-equilibrium state (liquid interface). It can also be used to determine the interfacial pressure of different fluids (liquid-gas interface).

Working principle

When pull Pt circle out of liquid sample, electromagnetic force -Balance Transducer will detect the maximum pulling force of Pt circle and the force can turn to tension value with formula as follows:
M=mg/2L   L= Pt circle's circumference
The test value will effect by many factor:
(1)Pt circle's average radius and the Pt wire's radius
(2)Liquid sample and other medium's density contrast
(3)Liquid sample's purity
(4)ambient temperature

Main Technical Features

1.It used electromagnetic force -balance-type transducer, improving the accuracy of the measurement
2.Demarcated one point and you can adjust the instrument, and it's very convenient.
3.the instrument can show current weight values and tension Equivalence
4.the instrument can revise the test result automatically
5.used high-quality screen, the life of screen extended
6.the instrument can save 255 records
7.the instrument has a mini- printer; you can print the test result any time.  
8.the instrument has RS232 interface equipment; it can connect to computer, and it convenient for data processing.

Main Structure

 

(1)screen                            (7) under-chassis;
(2)sample container           (8) RS232 interface
(3)Pt circle staff                 (9)fuse
(4)Pt circle                         (10)switch
