Blue-Green Algae Sensor

Hydrolab provides the most accurate Blue-Green Algae sensor available on a multiprobe.





Available in two forms, one for detecting phycocyanin (fresh water), and one for detecting phycoerythrin (marine water)
Ultra-compact size designed specifically for integration into the Hydrolab DS5X, DS5, and MS5
Available with solid Secondary Standards to provide a quick and simple method to verify the sensor's stability over time
The Secondary Standard can be adjusted to correlate to a known Blue-Green Algae concentration
Three auto-selected gain ranges provide a wide measurement range of 100 to 2,000,000 cells/mL for either phycocyanin or phycoerythrin




Identifies potential algal blooms before they become problematic, allowing time for corrective action
Less expensive and more timely than cell counting or visual inspection

Provides the most accurate measurement of phycocyanin or phycoerythrin because of electronic filtration of ambient light, efficient optical coupling and quality optical components
Incredibly fast response time through electronic filtration of ambient light
Excellent turbidity rejection due to small sample volume design and high quality optical filters
Cost-optimized for affordability and value
