Effective 04/28/2025 the Cyclops-7F has been discontinued

​

After more than two decades of trusted service, we are officially retiring our Cyclops line of submersible fluorometers. While this sensor has been a cornerstone in many field monitoring programs, the availability of critical components has diminished over time, making continued production no longer possible.

To support a smooth transition, we introduced the C-FLUOR line in 2019 as the next generation of fluorescence sensors. C-FLUOR offers enhanced sensitivity, faster response times, lower power consumption, and deeper deployment capability—rated to 2,000 meters with a rugged titanium housing and sapphire optical window. With options of both analog (0–5V) and RS232 digital output, and future MODBUS485 support, it’s designed for long-term success across diverse applications.

C-FLUOR sensors remain easy to integrate and are pin-compatible with many of the same systems that supported Cyclops units. Whether you’re working in water quality, aquaculture, or industrial monitoring, C-FLUOR delivers the reliable performance you’ve come to expect from Turner Designs.

We’re proud of everything Cyclops has accomplished and excited for what’s ahead. If you have questions about selecting the right C-FLUOR configuration for your application, we’re here to help.
