GDJ-1C Brookfield Rotational Viscometer
GDJ-1F ASTM D4402 Asphalt Rotational Viscometer is designed and made as per T0625 in the Industry Standard JTJ052 Specification and Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering, and ASTM D4402.
GDJ-1F ASTM D4402 Asphalt Rotational Viscometer is suitable to determine apparent viscosity of highway asphalt at a temperature from 45 °C to 200 °C as per Brookfield Viscometer Rotation Methods. The Asphalt Rotational Viscometer can also be used to determine construction temperature for bituminous mixture as per viscosity-temperature curve. The Brookfield Rotational Viscometer can also be used to determine viscosity of hot melt adhesive, oil grease, paraffin and high polymer. It can be widely used in cosmetics, food, pharmaceutical, dopes, chemical, and other industries.

Q1: What is the difference between LV and RV viscometer?
LV is for low viscosity materials and can measure the thinnest materials. Typical examples include inks, oils, and solvents. RV is for medium viscosity materials than those measured with an LV torque. Typical examples include creams, food, and paints.
Q2: What is Brookfield rotational viscometer?
The Brookfield Viscometer is the lab standard used around the world. Brookfield viscometers employ the principle of rotational viscometry - the torque required to turn an object, such as a spindle, in a fluid indicates the viscosity of the fluid.
Q3: What are the four types of viscometers?
Viscometers - More than Just One Measuring Method. Viscometers are categorized into capillary tube viscometers, falling ball viscometers, rotational viscometers, and vibration viscometers.
Q4: Which spindle is used in Brookfield viscometer?
All standard LV torque Brookfield Viscometers/Rheometers are supplied with a standard spindle set (LV-1 through LV-4) constructed of #302 stainless steel.
Q5: What is the difference between capillary and rotational viscometer?
Capillary viscometer methods are used to determine the viscosity of Newtonian fluids only. In contrast, rotational rheometer methods can determine the viscosity for Newtonian fluids and apparent viscosity for non-Newtonian fluids.
Q6: What is working principle of Brookfield viscometer?
The Brookfield Viscosity Meter instrument is a rotational viscometer. Driven by a motor, the spindle rotates at a constant speed. When the spindle rotates in a liquid, the liquid will exert a viscosity force moment on the spindle. The greater of the viscosity of liquid is, the greater of the force moment is. Otherwise, the less of the viscosity of liquid is, the less of the force moment is. The viscosity force moment can be measured by a sensor. You can get the viscosity of measured liquids after data process.
Adopts the microprocessor technique, the instrument can preset parameters (spindle No. and speed) conveniently, process test dada measured by the sensor, and show spindle No., speed, viscosity of measured liquid, and percentage of full scale, etc
