Hydrolab provides the most accurate Blue-Green Algae sensor available
on a multiprobe.
Features:
- 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
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 fluorometers available on a Hydrolab sonde:
- 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

| Corrosion resistance: |
Standard fluorometers have stainless steel enclosures that will
corrode in aggressive saline environments, such as oceans, bays,
and estuaries, and should not be used in these applications. For
sondes that will be used in saline environments, Hach Environmental
now offers fluorometers housed in titanium (DS5 and DS5X only) for
added corrosion resistance. Consult with your sales representative
for additional details.
