The BLUE FIT instrument measures the filterability index of inks, a key parameter for evaluating quality, stability, and suitability for industrial filtration. The Vmax value, obtained through testing, determines the maximum volume of ink (L/m²) that can pass through a filter surface before it becomes fully clogged, depending on the filter micron rating. This data allows assessment of filter clogging and supports the proper definition of filtration parameters.
The system includes a stainless steel tank, dedicated filter, portable scale, and Windows-based software for data acquisition and processing.
