[±5% ACCURACY] The viscometer uses a graduated disk, and the viscosity values are measured by moving the rotor rotation through the spinneret and spindle, has a large viscosity measurement range 10-100,000cps and the measurement error: ±5%, give your enough resolution to control my processes better. [ROTORS x ROTATION RATE] Different rotors (1,2,3,4) can be selected according to the viscosity range of different test liquids, and different speed (60,30,12,6) can be set. The knob adjustment is straightforward with a coefficient table on the top for easy reference. You can unlock more unknown liquid viscosity. [LIGHT WEIGHT BUT PRACTIALl] The rotary viscometer is light in weight, easy to move and operate flexibly. The helical gear lifting system effectively ensures that the viscometer can move up and down easily without sliding down by itself, which ensures the smooth progress of your experiment. [APPLICATION] NDJ-1 has been widely used to determine and measure the liquid viscosity in many application such as grease, painting, plastic, pharmacy and adhesives. There are no limitations about the liquid, just put the rotor into the liquid and test it. But the liquid you measure should NOT exceed 80℃ [GOOD WARRANTY] Viscosity meter tester is a precison instrument to monitor and control the stable quality of products in the manufacturing.The whole set of instrument has good quakeproof packing to ensure the precision of instrument. We also offer a one-year warranty. Buy at ease, use at ease.
