ME-NDJ-5S digital viscometer using 16-bit microcomputer processor as the core stepper with high-resolution drive, digital LCD with blue backlight digital viscometer. The speed is stable and precise. The keys are clearly marked. The program design, easy operation and alarm function, the screen directly displays the viscosity, speed, percentage of torque, rotor number and the maximum viscosity value of the selected rotor at the current speed. The main control board, subdivision driver board all using chip technology, circuit design using the most advanced microcomputer processor, the structure of a reasonable and compact layout. The full-scale instrument, the block all the linearity of the measurement through the PC interface calibration, measurement performance, function reached the advanced level of the same type.
