Digital Viscometer

Introduction

A technology that realizes single-turn multiple sampling. High subdivision drives the stepper motor to rotate, the speed is accurate and stable, and the frequency change of AC Voltage does not affect the accuracy of viscosity measurement. For thixotropic non-Newtonian liquids, the timing function of the instrument can ensure good consistency data. LCD liquid crystal with blue backlight function, directly display the viscosity, speed, percentage torque, and the measurable viscosity value of the rotor at the current speed. Viscosity values show a continuous change. There is an alarm sound prompt when the measurement range is exceeded.

FAQ

[Q]

Can I test the solder paste viscosity? 200Pa · s.

[A]

This one doesn't work, use NTV-S3.

[Q]

Meet ISO12634 Digital Viscometer

[A]

DV-79 Digital Viscometer, please refer to it.

[Q]

How should I choose the right rotor?

[A]

(1) General principle of measurement: high viscosity samples use small volume (G, F) rotor and slow speed, low viscosity samples use large volume (E, F) rotor and fast speed. The percentile scale (torque) of each measurement is between 10% and 90% as the normal value, and the viscosity value measured within this range is the correct value. (2) First estimate the viscosity range of the tested sample, then choose a small volume rotor and a slow speed according to the high viscosity sample, and a large volume rotor and a fast speed for the low viscosity sample. Generally, the rotor is selected first, and then the appropriate speed is selected. For example, when the rotor SP is E, the speed is 750RPM, and the screen directly displays the full scale range of 100mPa.s. When the speed is changed to 75RPM, the full scale range is 1000mPa.s. (3) When the approximate viscosity of the measured sample cannot be estimated, it should be set to a higher viscosity first. Try the rotor from small volume to large volume and the speed from slow to fast. Then each measurement is based on the percentile scale (torque) to judge the rationality of the rotor and speed selection. The percentile scale must be between 10% and 90% of the normal value. If it is not within this range, the Viscometer will issue an alarm to prompt the user to change the speed and rotor. Don't forget to change the rotor. Be sure to change the rotor number SP according to the selected rotor.

[Q]

Epoxy resin Coating viscosity measurement with what material Viscometer is better?

[A]

Measurement Coating viscosity generally can choose viscosity cup or Viscometer, viscosity cup mainly measures relative viscosity, Viscometer measures dynamic viscosity. In general, in addition to thixotropic Coating, Coatings under 150s can be coated with 4 cups, and Coatings under 20 can be coated with 1 cup. In addition, Yehui uses ISO flow cup to measure Newton-type liquid Coating viscosity, Stormer Viscometer to measure architectural coatings viscosity, and for all brush coatings, rotational viscometer or Cone and Plate Viscometer measurement can be used.

[Q]

What happens if the Viscometer is outside the measurement range?

[A]

When the current speed and the current rotor measurement range are exceeded, the screen will display and a beeping alarm sound will be issued. When the torque exceeds 100%, the percentage reading and viscosity reading are all EEEE.
