Hydrolab has partnered with
Turner Designs to provide a Blue-Green Algae sensor that uses fluorescence technology to provide real-time measurements of cyanobacteria.
Features:
- Available in two forms, one for detecting phycocyanin (fresh water),
and one for detecting phycoerythrin (marine water)
- Ultra-compact size designed by Turner Designs specifically for integration
into the Hydrolab DS5X, DS5, and MS5
- Available with Turner's unique 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
Benefits:
Real-time measurement:
- Identifies potential algal blooms before they become problematic, allowing time for corrective action
- Less expensive and more timely than cell counting or visual inspection
Plus, like all other Turner sensors
- 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
