viscometer Model:NDJ-5S Digital Viscometer

1、 Purpose:
This instrument can measure the absolute viscosity (dynamic viscosity) of Newtonian liquids. Widely used in industries and research institutions such as oils, paints, food, pharmaceuticals, adhesives, cosmetics, etc. (Optional constant temperature bath)
Technical indicators:

Viscosity measurement range: 100000 to 100000 (mPa · s/cP), equipped with rotor 0, with a measurement lower limit of 1mPa.s/cP

Speed: 6 revolutions per minute, 12 revolutions per minute, 30 revolutions per minute, 60 revolutions per minute (without gear drive)

Standard rotor quantity: 4 types

Measurement accuracy: ± 1.0% (full scale)

Reproducibility: 0.5% (full scale)

Input voltage: 110V/220V

Input frequency: 50Hz/60Hz

Optional accessories:

Ultra low viscosity adapter (rotor 0), micro printer, constant temperature water bath, RTD temperature probe, remote control, standard oil

Technical advantages:

1: The high subdivision drive stepper motor rotates accurately and steadily, and the frequency change of AC voltage does not affect the accuracy of viscosity measurement

2: The stepper motor is directly driven, with no noise, easy speed change, clear speed display, good reliability, and no shaking phenomenon

3: The LCD screen with blue backlight function directly displays viscosity, speed, percentage torque, and the maximum measurable viscosity value of the rotor at the current speed. The viscosity value shows continuous changes. There is an alarm sound indicating that the measurement range is exceeded

4: Computer full range linear calibration with measurement accuracy of ± 1.0% of full range

5: Switching power adapter, wide power input, good anti-interference performance

6: Optional RTD temperature probe for real-time monitoring of sample temperature

7: Optional RS232 interface, real-time printing of sample measurement data through a micro printer, saving labor
