500.135 - Deep sea profiling system for 6000 m depth:

Application:
The profiler can adapt to a lander system, and it can make water field measurements of micro profiles of for example O2, pH, H2S, N2O, H2, redox and resistivity. The profiler can be submerged to a depth of 6000 m and runs completely autonomously (demands additional software). The profiler comes with a robust and accurate motor system for profiling. Vertical resolution: 0,05 mm (0,025 mm on request).

General:
With many years of experience in adapting sensors and electronics for rough conditions and a strong collaboration within submarine instrumentation with Unisense, we offer a high quality solution for micro profiling and incubation studies in the deep sea. The rack has room for a battery cylinder and various electronics. We do not provide any software but the profiler comes with schematics so you can design your own interface.

In this video, Dr. Kanchan Maiti, associate professor in the LSU Department of Oceanography & Coastal Sciences, discusses how the microprofiler works and what the samples it collects can tell us about our wetlands.
