Fermentation is a black box. What exactly is going inside those tanks?
By continuously measuring gravity, pH, temperature, pressure, dissolved oxygen, conductivity and ambient temperature and ambient pressure, Sennos state-of-the-art sensors give brewers a look inside their tank, with a simple instrument that inserts through the fermenter’s sample port and stays in place with a standard tri-clamp.
This trove of data, coupled with Sennos’ app, gives brewers a movie of their fermentation instead of a handful of snapshots. Sennos promises better control of fermentations, proactive problem solving and better beer quality.
