The Smart Brine Viewer by Olen

Thanks to our close links with this sector, we have been able to identify improvement opportunities.


Faced with the regulatory constraints on freezing fish in brine and the lack of technical data to control the freezing process, the idea of developing a smart supervision system emerged. Olen launched a system dubbed the “Smart Brine Viewer”, which measures temperature and salinity continuously.
