A21Digital Brookfield Rotational Viscometer ASTM D4402
A21 Laboratory brookfield rotational viscometer
Standard:ASTM D4402
Application:
The asphaltBrinell rotational viscometer manufacturingis according to standard of ASTM D4402.
It has applied rotary process to test the apparent viscosity of asphalt road in the temperature range
above 45 ℃, by milli-Pascal seconds (MPa. s). According to the measurement results, we can find
out the recommendedmixing and compactionconstruction temperatures.
Compared withsimilar products,with high accuracy,stable viscosity value display, easy to read, easy
to operate, good anti-jamming performance advantages.Specially used to measrue apparent viscosity
of the asphaltroad. Also used to measure the viscosity of hot melt adhesive,wax, polymer and other fluids
