Normally it takes 6-13 business days to arrive once your order is confirmed.
Principle: The viscosity of the LND-1 viscosity meter is measured in time. A certain amount of samples will flow out of the holes within seconds at a constant temperature. Convert the time of seconds (S) to dynamic viscosity value (mm2 / s) of sample using the following formula: (t-6.0) / 0.223 (30s≤t≤100s), T Flow Time (s)Gama viscosity (mm2 / s)
