ZNN-D12 Rotational viscometer

ZNN-D12 ,12 -speed rotational viscosimeter is mainly used for the fast viscosity determinationin of drilling fluid, you can draw flow curev according to the multi-spot testing data to confirm the flow pattern of the tested fluid, it is maily for viscosity determination of non-newtonian fluids.
