Cyclops 7

The CYCLOPS-7™ combination of price, performance and size makes the sensor very attractive for oceanographic, freshwater and dye tracing applications.

CYCLOPS-7™ was designed specifically for integration into any platform that supplies power and datalogging.

  • Extremely small size - 5.7" x 0.9" s/s or Ti. 5.7" x 1.25" (Delrin)

  • Affordable price / excellent value
  • Built-in light scatter rejection
  • Low power consumption
  • Integrates into a C6™ Multi-Sensor Platform™ or any third-party platform
  • Interfaces with DataBank™ Datalogger
  • Cyclops-7 Submersible Logger Available
  • Cyclops Explorer enables various lab applications
  • No Housing version available for integration
  • Custom optics available : 260-900 nm

  • CYCLOPS-7 can be easily added to typical multiparameter systems within existing space constraints. Measurement capabilities are not compromised by using the CYCLOPS-7 compact sensor. In CTD/AUV applications, you can choose between a smaller battery pack or longer operation on each battery charge. Measurements can be made at any frequency and interval, as determined by an external data logger. Price barrier has been significantly lowered for adding a fluorometer to existing monitoring platforms.
