【Flow Viscosity Cup】This instrument is mainly used to determine the kinematic viscosity of Newtonian or near-Newtonian fluid coating. Can measure the viscosity of paints, coatings, water-based paints, adhesives, etc. 【Solid 】Brass viscosity cup, stainless steel outflow, no rust; brass screw switch and silicone gasket at the bottom of the cup, easy to close, firm. 【Accurate timing】There is a lifting fixing screw on the bracket, which can adjust the height of the viscosity cup for easy measurement and timing. 【High measurement accuracy】Seat structure, easy to operate, no need to hold up with the arm, avoiding fatigue while reducing manual errors, with a level, making the measurement more accurate. 【Viscosity Cup Parameters】Capacity: 100±1ml, Inner diameter: 50±0.2 mm, Discharge hole diameter Φ4±0.02mm, Efflux time(sec): 30-100s.
