The Cyclops Submersible Logger made by Precision Measurement Engineering, Inc.
(PME) is now available with an underwater connector to enable easy swapping of Cyclops sensors
. Users have the ability to quickly switch between Cyclops sensors in the field for collecting data across multiple applications.
The PME Logger records time, date, internal temperature, fluorescence or turbidity, and gain. Sampling rates can be adjusted by the user, with a minimum time interval of 1 minute. Data is stored on a removable SD card. The logger is a self-contained unit with a diameter small enough to fit into bore holes and other tight spaces. Data are offloaded to a computer via USB card reader for easy viewing and analysis. The package is powered by six AA lithium batteries; enough power for up to a year. The internal SD card has enough memory for 30,000 samples.
