Falling Rod Viscometer for ink
Falling Rod Viscometer (Laray Viscometer) for paste printing ink rheology test, compliant with ASTM D4040-10 and ISO 12644. Measure ink viscosity, yield value and shortness of paste inks and vehicles.
Description：
This unit is designed to measure the time it takes for a precision rod to fall 10cm. After several "fall times" are measured, the viscosity and yield value of the ink can be calculated by using the software included with the instrument or by using your own technique. This test conforms to ASTM D 4040-10 and ISO 12644 . “Standard Test Method for Rheological Properties of Paste Printing and Vehicles by the Falling-Rod Viscometer”
The basic system consists of the instrument stand, road and collar, and a 100 gm weight.
The instrument measures the time for a precision rod to travel 10 cm through ink sample. After multiple fall time tests, ink viscosity and yield value can be calculated by the matched software or your own rheology calculation method. It can also obtain ink shortness ratio to evaluate ink flow behavior for printing process.
