Vertical profiling systems


water profiler system

Profiling is the most cost-effective and efficient way to investigate the entire water column by collecting multiparameter data points at pre-programmed depths. YSI’s automated profiler systems can help you reduce the cost and time associated with monitoring, allowing you to collect the water quality data you need to quickly respond to events.

YSI Profilers are used for applications such as: selecting the right intake depth in a drinking water reservoir, understanding hypoxic events, detecting point and non-point source pollutants, evaluating the thermocline or pycnocline in a system, and early detection of harmful algal blooms.

Benefits of preventative maintenance


Routine maintenance can make all the difference in the performance of your equipment. Benefits include longer life expectancy for your instruments, less downtime, and better data in the field.
