COMPACT Adapt Yeast Monitor

Adaptable yeast concentration monitor

The COMPACT Adapt Yeast Monitor is a highly efficient and compact instrument tailored for real-time yeast concentration measurement during brewery processes. Capable of handling live yeast concentrations of up to 70% viable spun solids, this instrument offers accurate and reliable readings.

Primarily used for online measurement of yeast slurries in delivery pipelines, the COMPACT system provides real-time signals that can be utilised to trigger pitching and cropping operations. Additionally, it finds application in measuring yeast concentration in fermentation or propagation vessels.

Unlike the COMPACT Yeast Monitor, in which a probe has been integrated directly into the instrument, the COMPACT Adapt Yeast Monitor does not feature an integrated probe. Instead, a range of separate probes can be fitted, catering to various applications.
