Starting today, I will introduce to you some of the professional equipment used in our Zebung testing laboratory. The equipment that the Zebung testing engineer in the video is operating is a Mooney viscometer, which is used to measure raw rubber or mixed rubber. Equipment for mixing Mooney viscosity of rubber. This test is to check whether the rubber material meets the qualified Mooney value standard.
