Product details

Double cylinder digital viscometer Programmable digital viscometer

Technical advantages:

  1. It can be used standalone or connected to a micro printer and computer for data collection.
  2. By applying our company's invention patent, we have overcome the drawback of domestic instruments that can only sample once per rotation, and achieved the technology of multiple sampling per rotation.
  3. The high subdivision drive stepper motor rotates with accurate and stable speed, and the change in AC voltage frequency does not affect the accuracy of viscosity measurement.
  4. For thixotropic non Newtonian liquids, the timing function of the instrument can ensure obtaining good consistency data.
  5. Featuring humanized and personalized design, with 7500 continuously adjustable shear rates. It can synchronously display shear stress, shear rate, speed, viscosity, time, temperature, and the measurable viscosity value of the rotor at the current speed.
  6. Choosing DVLoad software allows users to download custom measurement programs to the instrument for fully computerized automation, or choose DV data acquisition and programmable analysis software for data acquisition and programmable analysis.
  7. The full range and linearity of each gear of the instrument are calibrated through a PC interface, and its measuring performance and functions have reached the advanced level of the same type abroad.
  8. The built-in RTD temperature probe monitors the sample temperature in real-time with an accuracy of 0.1 ℃ and a temperature range of 0-100 ℃.
  9. Different standard rotors can be selected as needed.
  10. Adopting a 16 bit microcomputer processor as the core, the stepper motor is driven with high subdivision and digital LCD with blue backlight function.
  11. According to the needs, standard materials from the metrology bureau can be selected to correct the viscosity meter, so that the inspection level is in line with international standards.

Technical indicators:

  1. Measurement range: 1-75 million cP.
  2. Speed: 0.1-750 RPM (continuously variable transmission) without gears.
  3. Rotors: 3 (E, F, G rotors) suitable for medium to high viscosity or 4 (A, B, C, D rotors) suitable for low viscosity.
  4. Measurement container: B container or A container.
  5. Measurement accuracy: ± 1% (full range).
  6. Reproducibility: ± 0.5% (full scale).
  7. Power supply: 110V/220V and 50Hz/60Hz.
  8. Optional accessories: Micro printer, dedicated viscosity constant temperature water bath, DV data acquisition and programmable analysis software, standard oil.
