Automatic Transformer Oil Interfacial Tension Tester

I.Automatic Transformer Oil Interfacial Tension Tester 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 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.

II.Automatic Transformer Oil Interfacial Tension Tester 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.

IV.Work 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
