Water matrix and objective
State water-plant intake, drinking-water source, aquaculture, surface water or landscape water and the algal trend to be observed.

Select online blue-green algae measurement by water matrix, turbidity and spatial distribution
PBA-800A uses pigment fluorescence for continuous blue-green algae measurement across 0–300,000 cells/mL, with a 200 cells/mL detection limit for source water, surface water and aquaculture.

01 · Start with the water
Evaluate algae distribution, turbidity and point layout together
The supplied sheet notes that blue-green algae can be non-uniformly distributed and recommends multipoint monitoring. It also documents turbidity below 50 NTU, so selection cannot rely on one cell-concentration value.
Concentration and turbidity
Provide minimum, normal and peak cells/mL plus normal and upset turbidity.
Points and mounting
Describe stratification, number and distribution of points, immersion location, pressure, mounting and maintenance access.
Interfaces and delivery
Confirm cable, 4–20 mA, relays, RS485, power, quantity and project destination.

Fluorescence blue-green algae analyzerPBA-800AOnline Blue-Green Algae Analyzer
A reagent-free fluorescence sensor for continuous blue-green algae measurement. Selection must consider uneven algae distribution, multipoint monitoring and the documented turbidity condition below 50 NTU.

03 · Operating applications
Typical blue-green algae monitoring applications
For water-plant intake, drinking-water sources, aquaculture, surface water and landscape water. Use multiple monitoring points where algae distribution is non-uniform.
Water-plant intake
Track blue-green algae changes in raw water before treatment.
Drinking-water source
Add continuous pigment-fluorescence monitoring to source-water protection projects.
Aquaculture
Observe blue-green algae trends in ponds and managed aquaculture water.
Surface and landscape water
Monitor lakes, rivers, reservoirs and managed landscape water.
04 · Common questions
Confirm this information before an inquiry
Why is multipoint monitoring recommended?+
Blue-green algae can be distributed unevenly, so one point may not represent the full site. The supplied sheet therefore recommends a project-specific multipoint layout.
Can it be used directly above 50 NTU?+
The documented condition is turbidity below 50 NTU. Higher-turbidity duty requires review of the actual sample and data before suitability can be confirmed.
Can the rhodamine B accuracy be converted to percent of reading?+
No. The source references the signal level of a 1 ppb rhodamine B dye sample, so the page preserves that wording.
Can the product image be used as a dimensional drawing?+
No. It provides consistent public presentation. Dimensions and mounting remain controlled by the specifications and project confirmation.
