Yuyao NDJ-1 rotary viscometer

 NDJ-1 rotary viscometer NDJ-1 rotary viscometer is used for the viscous resistance of the liquid dynamic viscosity measurement of liquid, widely used in the determination of various fluids oil, paint, plastics, food, drugs, cosmetics, adhesives, etc. viscosity is monitored and controlled production of product quality and stability of precision instruments. Structural principles and characteristics As shown, the instrument at a steady speed of rotation by the synchronous motor, connected scale disk, and then through the springs and shaft to drive the rotor rotates, if the rotor resistance of the liquid is not subject to, the gossamer pointer and scale disk 1 with the speed of rotation, the pointer on the dial noted reads "0." Conversely, if the rotor resistance by the viscous fluid, the springs produce torque, and viscous resistance to contend final balance, when the gossamer connection pointer certain readings (ie springs torsion angle) on the scale disc. The readings are multiplied by a specific factor to obtain the viscosity of the liquid. Instrument speed from the gear system and the clutch for shifting through the speed control knob, points fourth gear speed, as determined by the need to select. Instrument according to different specifications with four rotor 1 to 4, or 0 to 4 five rotor rotational speed can be accompanied with selected according to the level of the measured liquid viscosity. Instrument is equipped with a fixed pointer control mechanism for accurate readings with, when rapid time speed (30 rev / min, 60 rev / min) can not be read during the rotation, then gently press the cursor lever so that the pointer is fixed down for easy reading. Protection framework for stable measurement and protection for the rotor. Use protective frame determination can achieve a more stable measurement results. Extension of the cable to facilitate the liquid to be measured when the container is large and has a low level, and the measured liquid temperature is too high case, (using an extension of the cable can not be accurately measured). Instrument with a fixed bracket and lifting mechanism, generally carried out in the laboratory and a small amount of constant temperature measurement should be fixed. The instrument is fixed on the stand in order to ensure measurement accuracy. Instrument can also be hand-held use. (If, when ordering, or ordered separately) 0 rotor viscosity less than 100 or less, is used as reference measurement. This instrument has a helical gear and damping lifting mechanism, instrument smooth movements. Set of instruments with good shock package in order to ensure that the instrument of precision.
