PhytoFind™ is an in situ Algal Classification tool that distinguishes among algal groups using specific fluorescence signatures. Real-time abundance estimates are calculated for PE-containing algae (mixed group), PC-containing algae (Cyanophyceae), andtotal algae (all other algal groups). Calculations include an automatic correction for interference from dissolved organic materials (DOM) providing more accurate real-time estimates. Optics are optimized to minimize interference from turbidity. Abundances are displayed and logged as group percentages along with temperature, depth, and chlorophyll (µg/L) concentrations.

PhytoFind is factory-calibrated; no calibration standards or tools are required. Solid-state optoelectronics ensure long term instrument stability and reliability. Factory-installed temperature and depth sensors are included in the standard PhytoFind package. A mechanical wiper can be factory installed to minimize biofouling on optical components. The durable delrin housing is highly resistant to harsh environments and additional antifouling materials such as copper can be purchased for long term deployments. A large capacity for internal memory storage (over 60,000 data points) and a high capacity (6600 mAh) external submersible lithium ion battery make the PhytoFind an ideal instrument for almost any environment or application.
