This machine has expanded the computer direct-operation function on the basis of DL-6M so that users can directly operate the centrifuge by PC. DL-6MC not only possesses all DL-6M functions but also is characterized by the followings: 1)More simple and easy to operate; 2)Functions are further strengthened; 3)It can shows the Acc/Dec curves, integral curves and temperature curves; 4)It can store each parameter implemented by centrifuge in ten years, which is convenient for users to check; 5)It can be operated by both PC and panel of centrifuge for convenient; 6)It also can be linked into the networks to realize the local computer system management; 7)Manufacturer can visit user's centrifuge, diagnoses the trouble and then supply maintenance through internet.
