Abstract (en)

[origin: WO9518368A1] Method and arrangement for measuring the cleaning capacity of a cleaning bath, the light absorbing ability of which is dependent on both the content of cleaning substances and the degree of impurity, as well as the temperature. The light absorbing ability of the solution is measured at at least two different selected temperatures and with varying quantity of added oil. The remaining cleaning capacity of the bath is determined as corresponding to the quantity of oil which is added to the bath when the difference in light absorption at the warm and the cold temperature has reduced to zero.
