Turner Designs CyanoFluor Handheld HAB Indicator

Early identification of harmful algal blooms (HABs) is important for protecting public health. CyanoFluor™ is a field-portable fluorometer, which can quickly estimate the abundance of cyanobacteria in a mixed algal population using PC (phycocyanin) to CHL (chlorophyll) ratios. Monitoring PC to CHL ratios over time enables users to predict the onset of HABs and leverage resources to mitigate their harmful effects.

Raw water samples can be quickly analysed with results displayed in less than 30 seconds. Simply insert a cuvette with your sample and press READ. PC:CHL ratios are displayed and logged and can be downloaded at a later time.

CyanoFluor is factory-calibrated meaning no calibration is required; RFU values can be correlated to µg/L using conversion coefficients. Solid-state opto-electronics ensure long term instrument stability. CyanoFluor’s intuitive functions, small size, and internal data storage make it an ideal field instrument for HAB monitoring.
