YSI has all the tools necessary to effectively monitor and manage your aquaculture operation. YSI's spot sampling handheld water quality instruments allow for a quick check of water conditions, while our continuous multiparameter and DO monitors can aid in process control for your entire facility. YSI monitors can assist with your operation's feeding cycle via our Feed Smart™ timer and aid in the overall management of your facility with the facility mapper included with AquaManager software. AquaManager also allows you to easily view real-time water quality conditions remotely via PC or through the AquaViewerII app. Additionally, alarms can be set when conditions fall below user-defined standards, quickly alerting facility management of the condition so they can respond quickly to the change in conditions.


YSI Analyzers are used in biofuels, biotech and bioprocessing applications around the world and are often referred to as the "work horses" of the lab. Lab managers like that YSI analyzers are reliable, provide fast, accurate results, and require minimal operator training. YSI analyzers measure important nutrients like glucose, glutamine, and methanol; and can monitor the level of potentially harmful byproducts like lactate and ammonium. Biopharma uses YSI rapid electrode-based measurements to both monitor and control processes.YSI analyzers measure xylose and glucose to monitor fermentation progress in cellulosic ethanol research and measure residual ethanol during distillation in production facilities.

General & Environmental Lab

All sampling applications require the collection of high-quality data, but the demand for accurate data is perhaps greatest in the laboratory setting. Confidence in laboratory results is paramount, as this data is used for EPA reporting of parameters such as biochemical oxygen demand (BOD) of wastewater. Lab-obtained data is also commonly used in wastewater process control and verification in addition to drinking water analysis, publication, clinical research, and many other applications.
