BioPAT^®Fundalux is an absorption-based photometric probe that uses light from 840nm to 91nm to measure the turbidity in bioreactors and fermenters. A precisely defined and constant LED light beam passes through the process medium from either side of the gap on the probe’s shaft.

The probes have a connection of 12mm or 25mm and are available in a selection of optical path lengths of 1mm, 5mm and 10 mm.
