WebThe corresponding measuring device is called a densitometer ( absorptiometer ). The decadic (base-10) logarithm of the reciprocal of the transmittance is called the absorbance or density. [1] DMax and DMin refer to the maximum and minimum density that can be produced by the material. The difference between the two is the density range. [1]
