Introducing the Biolin Scientific Force Tensiometer Sigma 702ET

Sigma 702ET is specifically designed for the quality control of transformer oils. It follows IEC 62961 and ASTM D971 standards to measure the interfacial tension between a transformer oil and water as a quality control measure for the oil.

Accurate measurements of

  • Interfacial tension between transformer oil and water
  • (IEC 62961 and ASTM D971)
  • Surface tension
  • Interfacial tension
  • Critical micelle concentration (CMC) (manual)
  • Density

Quality Control of Transformer Oil

Testing interfacial tension of oil and water with the ring method.

The IEC 62961 and ASTM D971 standards are used to determine the possible contaminants of hydrocarbon fluids. The purity of hydrocarbon fluids is important in many industrial areas, such as in aviation, diesel fuels and transformer oils.

It is well known that oil-water interfacial tension correlates with the purity and functionality of oils that are used in transformers for cooling, insulation and protection against arcing. Electrical stress and contamination may modify the oil performance.

Sigma 702ET with a platinum Du Noüy ring is an excellent choice for controlling the oil quality according to IEC 62961 and ASTM D971-12 standards.
