Portable Rotational Viscometer, Digital Rotary Viscometer with LCD Large Screen and 4 Rotors, Digital Lab Viscometers Tester Meter for Paint Viscosity Testing,NDJ-9S

• 【LIQUID VISCOSITY MEASUREMENT】 The rotational viscometer is a new instrument for determining liquid viscosity and absolute viscosity.
• 【PARAMETER】Digital display NDJ-5S, measuring range: 10-100,000 mPa.s; digital display NDJ-8S, measuring range: 10-2 million mPa.s; digital display NDJ-9S, measuring range: 10-6 million mPa.s.Measurement accuracy: ±3% (Newtonian liquid).Rotor speed: 6, 12, 30, 60 rpm
• 【DIFFERENT ROTORS】 The rotary viscometer is equipped with four viscometer rotors. Depending on the viscosity range of different test liquids, different rotors can be selected and different speeds can be set.
• 【WORKING PRINCIPLE】Synchronous motor rotates at stable speed, connects dial, through spiral spring and rotating shaft, drives the rotors to rotate. Due to the liquid viscosity hysteresis, the rotors are subject to a torque proportional to the liquid viscosity measured by the sensors and processed to the viscosity and shown on the display.
• 【VARIOUS APPLICATION】 It is widely used in liquid, semi-liquid production industries and scientific research units, such as oils, paints, coatings, sludges, textiles, food, pharmaceuticals, adhesives, cosmetics.
