Dirt count in a sheet of paper

The SIMPATIC LABO is a laboratory sensor dedicated to a precise dirt counting on :
- a sheet of paper (by reflected light)
- a pulp sheet (by transmitted light)

A reliable and powerful tool
PC + scanner (A4)
Detected objects
Black spots (63 µm)
White or grey spots
Shives

Quick measurement and calculation (for a 10 samples range you need less than 10 minutes).
Calibration of the measuring system according to the EFPG standard (CEN/TC 172).

A friendly software


Meets all the criteria of the dirt calculation standard
The adjustment of the future ISO stnadard with regard to dirt counting has exposed some flows in existing counting equipment.
Samples of paper recently tested with 6 different pieces of equipment have widely varying results.


The standard imposes a set of recommendations aiming at avoiding any fluctuation due to measurement equipment. The standard stipulates among others :
-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 the detected spots
-The detection contrast must be compared to the local contrast of the spot (1 cm ring around the spot).
All these parameters are in SIMPATIC LABO.
