In many circumstances it is not possible to use a 400 ml beaker container when measuring viscosity with a Nirun viscometer. If moving these fluids is cumbersome or time consuming, there will be a need to use different containers. Sometimes, in order to avoid additional cleanup, we will not use the protection frame.
All of the above conditions require recalibration of the viscometer to obtain accurate viscosity data.
If you measure a set of viscosities, but only want to measure the viscosity of the same sample under different conditions, just do the following steps:
(1) Put the samples in the same sample tank, and also use the stand or not use the stand. Note that the same rotor and speed must be used and kept at the same temperature.
(2) Note down the new reading as a new reference point.
When the viscometer is used for quality control, this step can establish a method of control, and the operator does not need to know the true viscosity of the sample at this time.
If you need the true viscosity of your sample and don't want to use a tripod, follow these steps:
(1) According to the operation steps introduced at the beginning, measure the viscosity of Newtonian fluid, and use the standard sample tank. We strongly recommend using the standard viscosity samples provided by Nirun at this time. Be careful with the measurement steps, as the final result depends on it. Viscosity (mPa.s) of the fluid can be obtained by displaying the reading.
(2) Put this standard viscosity sample into the sample tank you want to use. Note that the temperature needs to be consistent.
(3) After the standard viscosity sample is used, try the used spindle and re-measure the viscosity in this new sample tank.
For example, adding solutes to printing inks will lower the viscosity value of the inks; and the added solute species can be used to control the rheological properties of the paint.
