Dose according to the degree of soil, and the water hardness.

On the basis of the measurement result made in the soil detecting photometric unit (20), moreover, a soil detecting unit (34) detects the degree of soil of the reaction container (21).

A method and system are disclosed for detecting an amount of soiling of a bill (1).

Optionally, sensors are used in order to determine a degree of soiling or the type of disruption.

The instructions shall specify how to make best use of the product according to the soil.

Dose according to the dosing instructions and use the dosage according to water hardness and degree of soiling

The invention relates to a method and device for checking the degree of soiling of bank notes.

The degree to which the sections (13, 14) can slide can be adjusted in accordance with the hardness of the water and the degree of soiling.

The dosages used shall be the recommended dosage for normal soil or normal use.

Amount of laundry, level of soiling, water hardness (ask your water

The frequency of cleaning is adapted to the level of contamination.

Wash at 40° or 60° depending on degree of staining.

depending on the water quality and the type of pollution

The resultant carpet tiles are subjected to a choosing step once again according to the degree of stains, etc.

The estimated polytropic efficiency is normalized (104) to render the estimate more indicative of the degree of fouling (106).
