NDJ-79 rotary viscometer - Zibo Bai Si-Automation Instrumentation Co., Ltd.

 NDJ-79 rotary viscometer, it applies to laboratories, factories measuring the dynamic viscosity and apparent viscosity of non-Newtonian liquids various Newtonian liquids, such as customized special drum and equipped with standard drum together, can be measured Rheological properties of non-Newtonian fluids. The instrument can measure the oil, resins, paints, pulp burnt, cosmetics, cream, medicines, asphalt viscosity. The equipment is small, light weight, easy to use, easy maintenance, durable, viscosity of the liquid can be measured quickly and reliably. The working principle of the instrument is driven by a miniature synchronous motor, which at 750 rev / min constant speed rotation. Motor shell with hanging installation, it rotates the shaft driven by the drum, when the drum is rotated in the liquid to be measured by the viscous resistance, counterproductive leaving the housing deflection, the motor housing with two root install a positive and negative metal springs connected to the rotatable housing makes springs produce torque moment when the two reach equilibrium, and is connected to the motor housing pointer will point out a certain value, this value and suffered viscous resistance to drum on the dial proportional, then multiplied by the scale readings drum factor, says the magnitude of dynamic viscosity.
