The Cyclops-7 logger utilises the high specification Cyclops-7 fluorometer from Turner Designs.
The Cyclops-7 logger connects to one Turner Designs Cyclops-7F sensor at a time.
The logger records measurements internally at a variety of possible sample rates, which are then stored to an internal SD card. Internal power allows the logger to operate for roughly 28,000 samples.
Data are then offloaded from the logger to a PC, via a standard USB cable for easy viewing and analysis.
The logger is completely self-contained and waterproof, with a diameter small enough to log within bore holes and other smaller diameter research spaces.
Two versions of the logger are available: interchangeable or fixed. The interchangeable logger allows the Cyclops 7F sensor to be removed and other Cyclops 7F sensors to be used. The fixed logger has a Cyclops 7F permanently hardwired in to the system.
• Replaceable Batteries
• 100 Meter Depth Rating
• Visualisation software included.
Each recorded sample includes the sensor measurement, time, date, logger battery voltage, and gain. The logger software automatically selects the appropriate sensor gain.
Design, construction, and material choice have been carefully planned to create the Cyclops-7 Logger. The outer case is constructed from Delrin, a hard and durable plastic material that does not easily crack or break. All internal circuitry and sensor components have been specifically designed to fit on the logger spine. The batteries, SD card, on/ off switch, circuit board and various other components are attached to a chem film aluminium spine.
Every Cyclops-7 sensor must be calibrated before use. The Cyclops-7 Logger software allows for the user to easily calibrate the sensor, but we recommend that standards be purchased from either PME or Turner Designs. These standards serve as references for calibrating the sensor.
For prevention of biofouling, a MiniWIPER is available for use with the Cyclops-7 logger. A small brush rotates over the sensors to perform a complete wipe over the sensors surface, then rests away from the sensor to enable accurate and continuous monitoring.
It can be programmed to wipe at various intervals (once every hour to once every 24 hours) and is powered by two AA Lithium batteries.
