☆ MV-C3 Mooney Viscometer
     Functions:  Prevulcanization,  Mooney Viscosity and Relaxation in one Machine!

MV-C3 Mooney Viscometer is used for measuring viscosity and relaxation of base rubber, raw rubber stock or rubber mass prevulcanization properties, it is also used for measuring viscosity in Mooney value for compounded or uncompounded unvulcanized natural, synthetic or regenerated rubber.

This instrument has excellent performances including automatic calibration, higher stability. It can perform the following tests: viscosity, scorch and stress relaxation.
