The Case: Turner Designs recently introduced several products addressing what it perceived as gaps in offerings available to the marine community – ICAM, an in situ absorption instrument requiring little or no correction for scattering; C-sense, a low cost, lightweight, low power pCO2 sensor; and Ballast-Check, a field-ready, handheld instrument for ballast water compliance monitoring.

The Company
Turner Designs provides innovative optical-based solutions for environmental research and monitoring, water quality analysis, and pollution control analysis. Having a unique focus on fluorescence instrumentation for over 41 years and customers throughout the world, Turner Designs is the leader in filter fluorometer design, manufacture and support. Turner Designs is known for providing rugged, reliable, stable instruments. It offers submersible, field, handheld, laboratory and online optical instrumentation varying in functionality, size, and price to fit any type of user need. It holds several patents for product innovations.
The Tech
Moving beyond fluorescence to provide researchers with additional measurements for better characterization of aquatic habitats, Turner Designs is expanding its repertoire of optical instruments with several recent product introductions. It introduced ICAM, an in situ absorption tool which requires little or no correction for scattering and C-sense, a small, low power in situ pCO2 sensor. In addition, it developed Ballast-Check, a handheld active fluorometer ideal for ballast water compliance monitoring.
It continues to provide numerous standard fluorescence configurations: in vivo and extracted chlorophyll; blue-green algal pigments such as phycocyanin and phycoerythrin; active fluorescence for determining yield; dissolved organic matter (algal as well as terrestrial); ammonium; optical brighteners and tryptophan for wastewater monitoring; dye tracers; crude and refined oils as well as infrared wavelengths used to detect turbidity. Custom optical configurations are also available. Package configurations include submersible, handheld, field, laboratory, online, and ready for integration into vehicles.
Submersible to depths of 6000 meters, instruments can be configured for depth profiling, long-term monitoring and horizontal mapping with GPS-integration. Data acquisition is available both real-time and via datalogging. Solid secondary standards enabling quick instrument verification and calibration checks are known to hold their value over several years of usage.
