NDJ-1S Digital Viscometer
Product Name: NDJ-1S Digital Viscometer Product Introduction: The NDJ series (NDJ-1S/NDJ-5S/NDJ-8S/NDJ-9S) digital viscometer has the characteristics
Product details

Product Name:NDJ series digital viscometer

Main Features

*The measurement data is displayed directly on the LCD screen without the need for secondary calculation.
*Adopting a 16 bit microcomputer processor as the core, the stepper motor with high subdivision drive and LCD backlight display.
*Using programmable motor control, changes in mains frequency do not affect measurement accuracy.
*The whole machine is designed with one machine, making it easy to operate.
*The instrument can provide a low viscosity option "0 rotor" for precise testing of viscosity values ranging from 0.1 to 100 mpa. s.
*You can choose a temperature probe to measure the temperature of the tested sample in real time.
*Equipped with RS232 interface (or optional USB 2.0 interface), it can output data and connect to external devices.
*Optional data processing software can be used to record in real-time the changes in viscosity with time, speed, rotor (shear rate), and temperature, providing a good method for understanding the viscosity and rheological properties of non Newtonian liquids.
Note: Digital viscometers can measure the viscosity of Newtonian liquids or the apparent viscosity of non Newtonian liquids. If viscometer data processing software is used, the rheological properties of non Newtonian liquids can also be analyzed.
