The CTD Profiler from D‑2 Inc. is a high‑accuracy marine profiling instrument engineered to measure conductivity (salinity), temperature, and depth with remarkable precision. Its flow‑through closed‑field conductivity cell offers laboratory‑grade accuracy in a compact, quiet, and low‑power package, ideal for deployment on autonomous platforms, winched systems, or ship‑based profilers. Built to withstand challenging marine environments, the aluminum housing supports operations to 3,000 m, while the titanium variant endures depths up to 10,500 m, making it suited for both coastal and deep‑sea applications.
With a choice of 4 mA power options, onboard memory and battery support standalone missions, while real‑time output via RS‑232 or USB‑C enables immediate integration with external systems. The profiler delivers data at 2–30 Hz sampling rates, adjustable to mission needs. D‑2 Inc. also offers custom OEM designs, allowing seamless integration into your existing profiling platforms with minimal development time, fast turnaround, and cost efficiency.
