The PCE-TUM 20 is a turbidity meter with automatically switching measurement ranges between 0-50 NTU and 50-1000 NTU. It features an infrared LED light source with a wavelength of 850 nm and a photodiode light detector. The photodiode positioned at a 90-degree angle to the measuring ray absorbs the light reflected by the particles in the dissolution. Diffused light or Nephelometric measuring methods are used for the lower measuring range. For the higher measuring range, an additional photodiode is positioned at the opposite side; therefore, measurement is performed via the transmitted light method.
