IVS300 is designed with Ubbelohde viscometer as the core, compliant with relevant standards such as ISO, GB, and DIN. It provides a stable and uniform temperature field, and conducts accurate timing to meet the requirements of viscosity test. It is mainly used for viscosity testing of polymers in dilute solutions. Automatic measurement is its main function. With a precision-level measurement standard, simple pipelines, and strong upgrade ability, it can be upgraded to an automatic measurement + automatic cleaning mode.
