Science - Metrology / Trübungsmessung
German term or phrase: Lichtschwächungsmessung
Doch die genauen Ansprüche an ein optisches Trübungsmessgerät hängen vom gewünschten Messbereich ab. So ist die Messung diffus gestreuter Strahlung typisch für Trübungsmessungen im niedrigen Bereich, zum Beispiel bei Trinkwasser. Die Messung stark getrübter
Proben, etwa bei naturtrüben Bieren, erfolgt hingegen als** Lichtschwächungsmessung** (Dämpfungsmessung) in Transmission, wofür das Gerät mindestens zwei Detektoren besitzen muss.

The Internet is no help. Also no hits for a literal translation. Anybody out there who knows? Thank you in advance and have a pleasant weekend.

light obscuration measurement


Explanation:
light obscuration
https://context.reverso.net/translation/english-german/light...

Measurements are in agreement between the two techniques when the beads are suspended in water. However, significant under-sizing is seen for the light obscuration measurement in the higher refractive index ethylene glycol mixture, while flow microscopy results are almost unaffected. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2895433/

Turbidimetry and light obscuration profiles were recorded as a function of agitation and shearing with and without the introduction of foam into the solutions
The impact of foaming was significant, resulting in an increase of turbidity and light obscuration measurements in all solutions. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3066372/

light attenuation measurement


Explanation:

The Standard Reference Method or SRM[1] is one of several systems modern brewers use to specify beer color. Determination of the SRM value involves measuring the attenuation of light of a particular wavelength (430 nm) in passing through 1 cm of the beer, expressing the attenuation as an absorption and scaling the absorption by a constant (12.7 for SRM; 25 for EBC).
https://en.wikipedia.org/wiki/Standard_Reference_Method

The color of beer is an interesting topic. Beer color is measured on an SRM scale, which stands for “Standard Reference Method.” SRM is measured by passing a beam of light (at 430 nm wavelength) through 0.39 inch (1 cm) of beer and measuring attenuation of the light. The 430 nm light used corresponds roughly to a blue-violet light.

The Standard Reference Method or SRM is a system modern brewers use to measure colour intensity, roughly darkness of a beer or wort. The method involves the use of a spectrophotometer or photometer to measure the attenuation of light of a particular wavelength, 430 nanometres, as it passes through a sample contained in a cuvette located in the light path of the instrument.
The EBC convention also measures beer and wort colour, as well as quantifying turbidity (also known as haze) in beer.
