Model: ADG-A1

This instrument provides automatic visual analysis for rapid, comparative and quantitive assessment of filler dispersion in rubber, which may affect many properties including abrasion resistance, tensile strength, tear strength and fatigue resistance. 

By utilizing oblique illumination of 30 degrees on the sample, a rubber specimen freshly cut by razor blade, light hitting any agglomerates, is reflected into the sensor with magnification (optical range of 3-57 microns for standard model or 1-20 microns for high resolution model). The bi-level analysis with auto determined thresholds and particle diameter analysis are computed from the captured image.

Options: Standard model with optical range of 3-57 microns (FDG-A1s) · High resolution model with optical range of 1-20 microns (FDG-A1h) · High Manual cured sample cutter · Unvulcanised sample preparation unit.
