Welcome to SENTRY and thank you for visiting us to learn more!

We’re the first and only company to offer a real-time BOD and biomass health wastewater quality monitoring platform providing microbial performance data in facility locations never possible before. From untreated, variable wastewater at a treatment plant’ headworks (consumable BOD) to fluctuating anaerobic digester biomass (consumable VFA), our robust bio-electrode sensors provide early-on, always-on insights into biological processes that exist wherever water is used, stored, or treated.
