IT.200 Interfacial Tension Tester

The IT.200 Interfacial Tension Tester is a fully automatic instrument designed to measure surface tension (liquid–gas phase) and interfacial tension (mineral oil–water phase) using the ring method in compliance with ASTM D971.

Controlled by a microprocessor and featuring a large colour LCD display with optional printer, the IT.200 ensures precise, efficient, and user-friendly operation. Its high sensitivity and accuracy make it ideal for laboratories testing petroleum, lubricants, and dielectric fluids.
