Is the MFFT suitable for measuring resins containing substances such as graphite?
In most cases, products with graphite can still be tested with the MFFT90, but the following points should be kept in mind: If there are any doubts,

The term “viscosity” is a parameter that describes a fluids resistance to flow. This resistance is a measure of the friction and the forces of interaction between the layers of a fluid. This friction is apparent when one layer of fluid is made to move against another The greater the friction, the greater the amount of force required to cause the movement – known as “shear”.
The process of flow through an orifice can often be used as a relative measurement and classification of viscosity. This measured kinematic viscosity is generally expressed in seconds of flow time which can be converted into centistokes (cSt) using a viscosity calculator.
Manufactured from high grade aluminium alloy with stainless steel orifices (where indicated), the Rhopoint Flow Cups are available with a range of UKAS / ISO 17025 certified standard oils to confirm the flow cup is measuring within specification.
