Rotational Viscometer NVM-401 is stepless for debugging and can measure the super-high viscosity of the sample. It consists of a 5-inch color touch-screen display, a built-in Linux system, and ARM technology. With a measuring speed of 0.1 to 200 infinitely variable speeds, the system has a total speed of 2000 speed options. The device has 30 self-built groups of test programs and a real-time display of viscosity curves with printing data and curves.
