Fully Automatic High-Quality Transformer Oil Interfacial Tension Tester

JS-900 SERIES AUTOMATIC INTERFACIAL TENSION TESTER is specially used to
measure the interfacial tension between mineral oils and water under non-
equilibrium condition (Liquid-Liquid interface). It can also be used to
determine interfacial tension of various liquids (Liquid-Gas interface).

JS-900 Series Automatic Interfacial Tension Tester adopts the standard test
method for interfacial tension of oil against water by the Ring Method, which
meets not only the national standard of People’s Republic of China GB/T6541,
but also the international standard such as ASTM D971.

Interfacial tension measurements on electrical insulating oils provide a
sensitive means of detecting small amounts of soluble polar contaminants and
products of oxidation. A high value for new mineral insulating oil indicates
the absence of most undesirable polar contaminants. The test is frequently
applied to service-aged oils as an indication of the degree of deterioration.

MAIN FEATURES:
1. Large color LCD display screen, English prompt, menu operation, fully
automatic testing process.
2. Automatic temperature compensation within 25℃ to eliminate the influence
temperature imposes on tension value.
3. Functions of auto correction, auto testing, calculation, results
displaying, and storage under power off circumstance.
4. Main body is equipped with hurricane globe, which lessens influence
outside matters impose on testing results.
5. Automatic lift of the lift platform ensures a steady environment as well
as high accuracy.
6. JS-900 Series IFT Tester adopts enclosed magnetic pot type sensor and
multi-point calibration of uniform space technology, which improves the
repeatability and reproducibility of testing results.
7. JS-900 Series IFT Tester can work independently and can also realize
network management via connection with laptops or computers through USB or
RS232 interface.
