Professional technology teaches you how to choose a digital viscometer?

A digital viscometer is an instrument that displays viscosity numerically, usually using electronic or mechanical sensors to measure the resistance of a fluid. The following is a detailed introduction to the key points and precautions for digital viscometer selection:

select points

Measuring range: When choosing a digital viscometer, make sure that its measuring range meets the required testing range. Usually, the measuring range of digital viscometer is 1-1,000,000 mPa·s.

Accuracy: Accuracy of the viscometer is a very important factor. If accurate measurement results are required, a viscometer with higher accuracy should be selected. Usually, the accuracy of digital viscometer is between 0.5%-2%.

Measuring method: The digital viscometer can be measured by various measuring methods such as rotating, oscillating, and tilting cups. When selecting, the appropriate measurement method should be selected according to the characteristics of the sample and the test requirements.

Calibration and correction: In order to ensure the accuracy and reliability of the measurement results, the digital viscometer should be calibrated and corrected. Therefore, when choosing a digital viscometer, attention should be paid to whether it has convenient calibration and correction functions.

Precautions

Sample Preparation: Before testing, samples should be stirred or shaken thoroughly to ensure that they are uniform in temperature and free of air bubbles. If the sample is too thick, its viscosity can be adjusted by heating or diluting.

Temperature Control: The temperature of the sample has a great influence on the viscosity test results. Therefore, it is necessary to control the temperature of the sample during the test and standardize the temperature to that of the viscometer.

Measurement Speed: The measurement speed of a digital viscometer may affect test results. If accurate results are required, an appropriate measurement speed should be selected and kept constant during the test.

Instrument maintenance: In order to maintain the accuracy and reliability of the digital viscometer, regular instrument maintenance and maintenance are required. This includes operations such as cleaning, calibration and calibration.
