Simpascan Dirt Laboratory Analyzer
DIRTY LABORATORY ANALYZER FOR LARGE SIZED PAPER SAMPLES AND PULP SHEETS
> Quick analysis of dirt in pulp and paper large sheets
> Accurate dirt counting on :
> Powerful led illumination system
> Performs digital scan of individual pulp or paper sheets either by reflected light or by transmission according to ISO standards
> Detects any contrasting impurities such as shives, metal, plastic, grease, sand, etc
> Sorts detected impurities as black dots, gray dots and shives according to its color and shape
> Calibration of the measuring system according to the EFPG standard (CEN/TC 172).
USER FRIENDLY SOFTWARE
> Runs on standard controlling PC with Windows OS
> Measurement window
> Configuration window
11 configurable classes for size and contrast
Different configuration settings may be saved (e.g. ISO 5350, TAPPI T213, T437, T563 for simple change of measuring reference standard)
RELIABLE AND POWERFUL
> High resolution linear camera with 12.288 pixels
> Adjustable according to sheet dimensions, up to 83cm width and no limit for sheet length
> Resolution, pixel size 67μm for max. width (83 cm)
> Analysis time < 1 minute for a 80 x 80 cm sheet
> Repeatable and reproducible
MEETS ALL THE CRITERIA OF MAIN DIRT CALCULATION STANDARDS :
Digital dirt counting for substitution of classical visual analysis requires a set of ISO criteria to avoid fluctuation :
> Sampling management and information about the validity and relevance of the measurement.
> Individual examination of the calculated points must be possible.
> Calibration of the system via the EFPG chart.
> The detection contrast must vary with regard to the area of detected spots.
> The detection contrast must be compared to the local contrast of the spot (1 cm ring around the spot)
