Turner Designs’ FluoroSense

Turner Designs offers phycocyanin (PC) as an optical con- ? guration of its FluoroSense handheld ? uorometer to assist with identi? cation of PC containing algae typically associat- ed with Harmful Algal Blooms (HABs). Obtaining both PC and chlorophyll estimates helps in determining whether ad- ditional testing is required to check toxicity levels in a body of water. FluoroSense’s simple two-button keypad enables

There is no warm-up time required; chlorophyll or PC claims will revolutionize the way in which bathymetry and µg/L estimates are displayed in seconds. The FluoroSense imagery data is processed. CARIS Onboard automatically boasts an extremely lightweight, small, waterproof design, converts data as it becomes available and applies a range while offering a high degree of durability. With a very low of pre-determined corrections, the data can then be used to power draw, the FluoroSense can take more than 10,000 generate a terrain model or mosaic.
