YSI 6-Series Water Quality Sensors

Predict algae blooms and determine the nutrient loading in water with the YSI 6025 Chlorophyll Sensor.

The YSI 6130 sensor provides accurate, in-situ measurement of Rhodamine WT in fresh, brackish, sea water, stormwater, and wastewater.

YSI's 6131 blue-green algae sensor monitors algal populations at natural levels in freshwater, providing an early warning for bloom conditions.

YSI's 6132 blue-green algae sensor monitors algal populations at natural levels in marine water, providing an early warning for bloom conditions.

The 6136 Turbidity Sensor provides accurate, in-situ measurement of turbidity in fresh, brackish, and sea water, as well as other applications requiring highly accurate turbidity data.

YSI's Reliable Oxygen Sensor (ROX) is a luminescent-based DO sensor that provides accurate long-term measurements in severe fouling and low oxygen environments.

Included with virtually every 6-Series sonde, the 6560 provides reliable temperature and conductivity readings.

The YSI 6561 pH Sensor provides long life, good response time, and accurate readings in most environmental waters, including freshwater of low ionic strength.

Obtain unprecedented accuracy and reliability with the YSI 6562 Rapid Pulse Dissolved Oxygen Sensor.

Simple, accurate pH and ORP (Oxidation Reduction Potential) measurement in a sensor designed for minimal maintenance.

The YSI 6572 free chlorine sensor measures hypochlorous acid concentrations in drinking water.
