SNB viscometer is a common rotary viscosity measuring instrument, suitable for measuring the viscosity of various liquids, such as chemicals, coatings, paints, greases, etc. The following is a detailed introduction to the key points and precautions for SNB viscometer selection:
select points
Measuring range: SNB viscometers have different measuring ranges, usually expressed in viscosity units CPS (centipoise) or mPa·s (milliPascal second). Choosing the proper measurement range depends on the viscosity range of the liquid you want to measure, and you should choose a SNB viscometer with the required viscosity range.
Accuracy and repeatability: The accuracy and repeatability of the SNB viscometer are important indicators for selection. When choosing, you should check the accuracy and repeatability specifications, and choose a high-precision SNB viscometer.
Measuring temperature: Viscosity is closely related to temperature, so it is necessary to choose a SNB viscometer that suits the temperature range you need. Some SNB viscometers have a built-in temperature control system that automatically controls the temperature during the measurement.
Speed range: SNB viscometers have different speed ranges, usually between 0.1 and 200 rpm. Choosing the proper speed range depends on the viscosity of the liquid you want to measure, and you should choose a SNB viscometer with the required speed range.
Precautions
Calibration: Calibration is required before taking measurements with the SNB Viscometer. This can be done by using calibration fluids and following the calibration procedure provided by the manufacturer. The calibration process should be carried out periodically to ensure the accuracy of the SNB viscometer.
Cleaning: Before and after using the SNB viscometer, it needs to be cleaned. Use suitable solvents or cleaning agents, do not use strong acids or alkaline substances for cleaning, to avoid damage to the SNB Viscometer.
Operating temperature: Before using the SNB viscometer for measurement, the sample needs to be heated or cooled to the appropriate operating temperature. This can be done by heating or cooling the sample in a constant temperature Water Bath.
Measurement operation: When taking measurements, attention needs to be paid to the stability and repeatability of the operation in order to obtain accurate and repeatable measurement results. At the same time, before the measurement, it is necessary to ensure the measurement range, accuracy and repeatability of the SNB viscometer.
