E ach product has different reflective properties.
A ccording to the conductivity and the dielectric value of liquids, the
reflection properties can differ considerably. Therefore additional
options such as "Solvent", "Chem. mixture" and "Water based" are
offered below the menu item Liquid.
T hrough this additional selection, the sensor is adapted perfectly to the
product and measurement reliability, particularly in products with bad
reflective properties, is considerably increased.
