Profiling Floats

nke Instrumentation has extensive experience in the design and the manufacturing equipment useful for oceanographers’ studies of the evolution of oceans and climate. The company benefits from a technical team specialized in the development of profiling floats and allows NKE Instrumentation to offer to its customers various types of floats.

The PROVOR CTS5 Profiling Float by NKE

Standard profiling floats (ARVOR and PROVOR)
Bio & specific profiling floats
High & low depth profiling floats

BGC-ARGO compliant for R&D and demanding applications.
The PROVOR CTS5 -with camera- design is based on the ARGO PROVOR CTS4 float to integrate additional sensors to the standard CTD. These are optical sensors from Satlantics, WetLabs or Aanderaa.

Underwater Altimeters and Depth Sensors

Underwater Altimeter & Echo sounder by ImpactSubsea

Underwater Altimeter & Echo Sounder with optional Pitch, Roll & Heading (AHRS)

Optionally available on the ISA500 is an integrated Attitude & Heading Reference System (AHRS) providing Heading, Pitch & Roll.

The AHRS is based on Micro-Electrical-Mechanical-System (MEMS) based technology.

Within the ISA500 there are three MEMS based Gyros, Accelerometers & Magnetometers. The outputs from each of these MEMS devices are fused together, providing highly stable Heading, Pitch & Roll.

The Heading is highly resilient against temporary magnetic interferes. This is aided by a soft and hard iron calibration feature once the unit has been installed on the ROV, AUV or other underwater application.

Fluorometers, Active Fluorometers and Turbidity Sensors

VLux AlgaePro

VLux AlgaePro is the latest advancement in in situ fluorometers from Chelsea Technologies, measuring 4 algal groups with integrated environmental corrections for absorbance and turbidity in one compact sensor. The absorbance measurements also provide a correction for CDOM interference and increase dynamic range by a factor of 20x.
