About Turner Designs
Turner Designs has been a leader in the manufacture of fluorometers and optical sensors for more than 40 years. Our instruments are used worldwide for oceanographic research, water-quality monitoring, and environmental analysis — wherever precise fluorescence measurement matters.
Field & lab fluorometers
Submersible, handheld, and benchtop instruments for chlorophyll, dye tracing, and turbidity.
Research-grade optics
Stable, sensitive detection trusted by universities, agencies, and industry labs.
Ocean & water monitoring
Solutions deployed across oceans, lakes, and municipal water systems.
Environmental commitment
Durable, long-life instruments designed to reduce waste and support sustainable science.
Our demo & loaner program
We know the best way to evaluate an instrument is to run it in your own application. Our demo and loaner program ships serialized units to your site for a defined evaluation period, with full tracking of condition, accessories, and return. This system keeps that program organized — so the right unit is always available and every loaner is accounted for.
