YSI's 6432AF blue-green algae sensor monitors algal populations at natural levels in marine water, providing an early warning for bloom conditions.

This sensor must be installed into a 6-Series sonde to function. Does not function on its own.

  • Overview

    Copper-based parts on the YSI 6432AF Blue-Green Algae Sensor repel aquatic growth on sensors, extending deployment periods.

    Blue-green algae (a. k. a. cyanobacteria) monitoring is of growing interest due to the problems some species can present through the production of toxins and compounds that deteriorate the quality of drinking water and through the formation of blooms. Blue-green algae are of interest for ecosystem studies and monitoring as well, where they may represent the most abundant primary producer.

    Features include:

    • Designed for marine (phycoerythrin) environments
    • Optimized for excellent sensitivity for monitoring algal populations at natural levels
    • Insensitive to potential interference including chlorophyll, turbidity, and dissolved organics

    The YSI 6432AF blue-green algae sensor is fully compatible with all YSI 6-series sondes equipped with optical ports.

    YSI's optical sensors use an integrated wiping system to provide anti-fouling in the most hostile environments. Durable mechanical features include a non-corroding titanium wiper shaft, replaceable wiper shaft seal, and a new switch controlled wiper parking system to prevent mis-parking.
