Cyclops Fluorometers easily integrated into AUVs, Gliders and Floats
|The Cyclops Integrator enables easy system integration of our popular Cyclops Submersible Fluorometer/Turbidimeter into AUVs, gliders, floats and other platforms. One, two, or three optical sensors with configurations ranging from deep UV to IR along with the Cyclops Integrator electronics can be built into a custom optical head defined by the customer or one of our pre-defined optical head configurations. Data is provided in a simple ASCII format, delivered at 1 second intervals only 3 seconds after power is applied. Standard optical kits are available for detecting: in vivo Chlorophyll, Crude Oil, Refined Fuels, CDOM/FDOM (dissolved organic material), Blue/Green Algae, Fluorescein Dye, Rhodamine Dye, PTSA Dye, Optical Brighteners, Tryptophan, and Turbidity. Cyclops Integrator packages can also be configured with custom optics for specialized applications per customer request. Sensors are pressure-rated to meet 600m, 1000m, or 6000m depths. Typical current draw is minimal, 100mA operational for three installed sensors powered with a 12V supply.
Ballast-Check Handheld Active Fluorometer
||The inadvertent introduction of invasive aquatic species when discharging ballast water has been known to cause both ecological and economic damage. Consequently, regulations are being established which specify the limits and monitoring protocol to detect living organisms released during a ballast water discharge. Treatment systems are being employed and the challenge of how to show compliance is under examination. One of the methods for determining compliance that is receiving a lot of attention is active fluorescence which looks at the viability of organisms in the ballast water. Turner Designs is excited to introduce the Ballast-Check, a handheld active fluorometer that provides a quick check indicating if ballast water is within compliance levels and appropriate for discharge. Designed with simple one-button readings and a risk assessment with each measurement, the Ballast-Check is an ideal instrument for ship owners or port state officials to quickly obtain independent verification that ballast water meets discharge requirements.
INSTRUMENTS IN ACTION
C3s travel from San Francisco to Australia!
||On November 17th, 2011, Liquid Robotics launched four Wave Gliders from San Francisco. Two were designated for travel to Australia and two were directed to Japan. Fourteen months later in January, 2013, the first Wave Glider, Papa Mau, arrived in Australia and in February the second, Benjamin, arrived. Configured with Turner Designs C3 Submersible Fluorometers, the wave gliders collected and transmitted chlorophyll, turbidity, & crude oil data throughout the journey. Data were accessible on the Liquid Robotics website including findings such as a 1200 mile chlorophyll bloom along the equatorial pacific. We haven’t seen Benjamin’s yet, but we think Papa Mau’s C3 looks pretty good for having been out at sea for fourteen months! Fontaine Maru & Picard Maru had a few mechanical issues but should be back in the water en route to Japan soon.
Deployment of the PME Logger designed for Cyclops-7 Submersible Sensors
|The new Cyclops-7 Logger, designed by Precision Measurement Engineering, Inc. (PME) was recently deployed near Clear Lakes, Idaho as part of a dye trace study. The PME logger is a self-contained submersible logger that auto ranges and records up to 28,000 data points on a removable SD memory card. After it was deployed at the site below (green arrow head), the logger system first indicated the detection of the Fluorescein dye about 18 hours after injection over a linear distance of about 2,150 feet for a maximum velocity of 119 feet/hour or 2,867 feet/day or 0.54 miles per day. >>Read More

PTSA as a UV Calibrations Standard
Turner Designs offers a UV line of optical sensors that are used to detect the fluorescence of Crude Oil, Optical Brighteners, CDOM/FDOM, or PTSA in water. Calibrations of these sensors are carried out by end users and require the use of a calibration standard to convert the raw signal output to actual concentration estimates. However, most standards used to calibrate UV sensors are toxic, extremely flammable, hard to handle, and may have strict regulations for disposal. To alleviate the risk and cost associated with handling hazardous materials for the purpose of standardizing UV fluorometers, Turner Designs offers PTSA (1,3,6,8-pyrenetetrasulfonic acid tetrasodium salt) as a liquid calibration standard. >>View Tech Note
NDSA as a Deep UV Calibrations Standard
Turner Designs offers a deep UV optical sensor used to detect Refined Oils and/or Fuels in water. This sensor uses an LED light source to emit deep UV wavelengths that are absorbed by Refined Oils or Fuels causing those compounds to fluoresce. The fluorescence response is detected between 325 and 375 nm wavelengths and is proportional to the concentration of Refined Oils or Fuels in water. NDSA is a fluorescent compound that emits wavelengths between 300 and 400 nm when irradiated with deep UV (< 300 nm) light. It is safe to handle, easy to dilute, neither toxic nor flammable, not reactive with other compounds, and non-hazardous. NDSA is an ideal lab standard that can be used to standardize fluorometers configured for detection of Refined Oils or Fuels in water. >>View Tech Note
Mysteries of the Solid Secondary Standard Revealed
|A Solid Secondary Standard is available for most Turner Designs fluorometers. Solid Secondary Standards provide a quick and easy way to validate instrument performance. Questions related to the Solid Secondary Standards are very common. I don’t think a day has gone by when I did not receive a phone call or email asking about our Solid Secondary Standards, so I hope to dispel some of the mystery and confusion surrounding them.
What are they made of? The outer black casing of the Solid Secondary Standard is made of delrin plastic and is very durable. The core of the Solid Secondary Standard is one of several stable fluorescent plastic materials. It holds up to the rigors of photo-decay and as long as it is stored under ambient conditions free from dust and humidity, it will provide you with stable consistent readings for many years. >>Read More
||DataBank Software and Firmware Upgrade: Version 3.08
We recommend customers who received their DataBank Handheld Datalogger prior to March 12, 2013, upgrade their current versions of software and firmware to the latest version 3.08 using the link below.
These upgrades should not affect calibration values or data stored on your DataBank instruments. The new 3.08 revisions are built with smoother data scrolling allowing for faster gain switching during data logging and enabling a quicker determination/estimation of sample concentration. These changes are built into the firmware so users are not required to change their normal operation of the DataBank.
NOTE: Some customers may receive error messages when installing the DataBank software. This occurs because the install process looks for program files that already exist on Windows computers. If you don't have the required files for the install process to complete, they will automatically be installed. If newer versions of program files used for the install process are found on your computer, you will get a prompt asking if you would like to Abort, Retry, or Ignore. We suggest hitting ignore so your current files remain intact. You may need to click Ignore three times during the install process.
CAUTION: Make sure that the DataBank battery is fully charged before attempting upgrade.
