Cyclops-7 & Cyclops-6k Submersible Sensors

Compact sensors designed for integration into multi-parameter platforms requiring high performance at a significantly lower price than traditional submersible fluorometers.

Product Description

Cyclops-7 & Cyclops-6k Highlights

  • Very small size
  • Low power consumption
  • Wide range of Optics and Custom Optics available
  • Depth ratings from 600 to 6000 metres
  • Integration with the DataBank logger, C6 Platform (Cyclops-7) or third-party systems


The Cyclops-7 is a single parameter submersible fluorescence which can be interfaced with the Turner Designs DataBank handheld display unit, the C6 multi-parameter platform or third-party systems (CTD’s or dataloggers etc). The high performance sensor offers an excellent level of turbidity and sunlight rejection ensuring sensor in the field and if necessary allow you to perform a calibration. The flowthrough cap combined with a Cyclops-7 creates a very simple on-line monitoring system capable of withstanding up to 50psi. The shade cap offers protection from direct sunlight during shallow water deployments and protects the sensor face from damage your data is not adversely influenced. Available with either a plastic, stainless steel or titanium housing.


The Cyclops-6k, the newest version of the Cyclops-7 Submersible Sensors, enables fluorescence detection to ocean depths of 6000 meters. Reinforced Titanium housing and a specialized optical head ensure sensor integrity at extreme pressures. The LED excitation source allows for low power consumption and excellent signal stability enabling long-term deployments. The introduction of the Cyclops-6K™ gives researchers a new, affordable tool for deep ocean exploration.

Optical Channels

Standard optics include: Chlorophyll a in vivo, Blue Green Algae (both Phycocyanin and Phycoerythrin), Fluorescein Dye, Rhodamine WT Dye, Turbidity, PTSA Dye, CDOM/FDOM, Crude Oil, Refined Fuels and Optical Brighteners. Custom optics can also be configured to suit your application.

A range of accessories to compliment the sensor are available such as the solid secondary standard, flowthrough cap and shade cap. The solid secondary standard provides a quick and robust means to confirm the stability of the
