The IV Tester is to determine the intrinsic viscosity also called solvent viscosity or intrinsic viscosity.
No chemical solvents are used in the determination. This method is used in particular for quality control of polyester (PET) or polyamide (PA).
The residual moisture has a considerable influence on the measurement result for certain test materials. Therefore, it is recommended to dry test materials before a IV measurement and to determine the residual moisture.
