Details of YD/NDJ-1A Paraffin Viscometer and High Temperature Viscosity Tester:

YD/NDJ-1AParaffin viscometer, high-temperature viscosity testerIntroduction:
YD/NDJ-1A high-temperature melt viscosity measuring instrument adopts 16 bit microcomputer processor as the core of stepper motor high subdivision driving technology, with program control, stable speed, and easy operation; The LCD screen can directly display information such as viscosity, speed, percentage torque, rotor number, and temperature of the measured liquid, and has functions such as error alarm. The equipment adopts advanced calibration technology, and the accuracy and linearity of each level are calibrated by an external computer using standard silicone oil of different viscosities, ensuring high precision, accuracy, and repeatability of the instrument. In addition, the equipment is equipped with a high-precision temperature control device, with a maximum temperature of 250 ℃ and a temperature control accuracy of 0.1 ℃.

Compliant standards
GB/T 2794-1995 Determination of Adhesive Viscosity
HG/T 3660-1999 T Determination of Melt Viscosity of Hot Melt Adhesive
And relevant standards for asphalt viscosity testing.
