PhytoFlash™ is an in situ Submersible Active Fluorometer that can be used to determine the quantum efficiency of phytoplankton in both oligotrophic and mesotrophic environments. The PhytoFlash™ is distinct from other variable fluorescence instruments on the market in that it is the first solid-state instrument capable of variable fluorescence measurements on natural concentrations of phytoplankton. The solid-state platform allows for a much wider range of uses due to the small size, power efficiency, more stable components, and lower price point.

Operate in three different modes
Integrate with a CTD
Self-contained with internal datalogging
Extended battery life - 30 second intervals for over 35 days

In September we welcomed many of our distributors from around the world to our new office for training. It was an exciting 3 days filled with lots of information about our newest products. We capped off the week with a fun-filled trip to Alcatraz Island and an evening in San Francisco.
Exploratorium in San Francisco recently held an open house highlighting new experiences that immerse their visitors in the bay & ocean environment. Turner Designs participated in the event by demonstrating and explaining how fluorescence works in an effort to help people understand the basic principles behind our new C6P Submersible Fluorometers, which will be deployed off an Explorato ...
The winners of the Liquid Robotics Wave Glider PacX Challenge deployed Honey Badger at the end of May on a 6 month mission called MAGI. The goal of this mission is to sample the late summer phytoplankton bloom that develops near the 30th parallel North (30oN). Honey Badger is configured with several Turner Designs instruments -- two C3 Submersible Fluorometers configured with Chlorophyll, CDOM ...
Introducing several new products last year is making this year particularly busy for everyone at Turner Designs. Our C-sense pCO2 sensor is getting a great reception from customers while our partners expand options for integration. Our red chlorophyll sensor is deployed at several sites and we should have good data sets to share soon. Ballast-Check 2, our Handheld PAM Fluorometer, will soon be w ...
Turner Designs is excited to announce our new distributor in Germany, terra4. Representing complementary products for over 8 years, terra4 is a valuable addition to our group of international distributors. Welcome aboard!
Here's a fun story about Turner Designs founder, George Turner:
George went to Charleston High School. After school he would search the alleys for “things of interest” that businesses had tossed in the trash. He would glean mechanical and electrical items and take them home to his workshop in his Dad’s garage. He put on his roller skates and tucked the items under one arm and with the ...
The ALS Ice Bucket challenge is nothing new but our president, Jim Crawford, added a nice touch when his name was called. Jim offered to donate an additional $10 per employee who chose to implement his torture. Needless to say, quite a few employees joined the fun and Jim ended up donating $200. Even though it was a beautiful California afternoon, Jim found the experience to be uncomfo ...
Congratulations to Corinne Gibble (University of California, Santa Cruz) and Jessica Corman (Arizona State University) on their Travel Stipend Awards for their presentations at last week's Joint Aquatic Sciences Meeting in Portland.

Last week our VP of Marketing & Sales, Pam Mayerfeld, had the opportunity to swim with a Liquid Robotics' Wave Glider in the beautiful waters of Hawaii. Pam said it was an amazing experience and gave her even greater appreciation for the Wave Glider's technology. >>Learn more about Liquid Robotics
Turner Designs hit the ground running in 2014 with several new product announcements at the top of our to-do list. We officially released ICAM, our Integrating Cavity Absorption Meter developed in conjunction with Texas A&M University. It’s been a long time coming and we appreciate all the interest expressed by customers over the years. We hope you will all agree it’s been worth the wait. In F ...
Next week we'll be exhibiting at both Ocean Sciences Meeting, in booth #22, and the Ballast Water Management Summit. If you are attending please stop by and say hello and we'll tell you more about our exciting new products!
We'll be exhibiting at AGU in booth #1236, December 9-13, 2013 in San Francisco, CA. We'll also be exhibiting at the Ballast Water Management Technology Conference at Congress Centre in London, December 11-12, 2013. When registering for the Ballast Water Management Technology Conference quote VIP Code: FKT2543TDWL to receive a 25% discount.
Summer is drawing to an end in the northern hemisphere and looking back on the year so far, it’s encouraging to see that water quality and environmental monitoring continue to be focal points for research around the world. Data provided by these efforts are critical to our quality of life. Turner Designs has been dedicated to supporting the scientific community for over 40 years and this year ha ...
If visiting San Francisco be sure to stop by the new Exploratorium at Pier 15 to see Turner Designs’ fluorometers in action. After more than 40 years in the Presidio, The Exploratorium recently relocated to brand new facilities and took the opportunity to add many new exhibits offering hands-on learning experiences. One of those exhibits, the Wired Pier, includes weather, air quality, an ...
Another 6 months have flown by and it’s time to touch base with you, our wonderful customers. It’s always amazing how quickly time passes and a challenge to pick the highlights to tell you. Posting news on our Web pages, Facebook & Twitter reaches many of you, but for others our newsletter is when you hear our updates. Hopefully you’ll find the news we’re sharing to be useful. We like ...
We’re sorry we missed you if you weren’t able to attend the National Water Quality Monitoring Conference in Portland last week It was a great meeting and we had lots of interesting conversations. Looks like customers attending the show were mostly interested in how easily we can customize sensors for different CDOM/fDOM applications as well as how our PhytoFlash Active Fluorometer can be used ...
Turner Designs is celebrating our 40th anniversary on February 18, 2012. We feel proud knowing we continue to offer great instruments and supportive service to a wonderful customer base after 40 years of business. Thank you to all our customers for keeping us strong after all these years together.
Turner Designs is excited to announce we are now granting travel stipend awards to students who present a paper or poster referencing their use of Turner Designs equipment. This opportunity is separate from our instrument donation program which will continue to award AquaFluor Handheld Fluorometer/Turbidimeters biannually in July and December.
We’ll be posting new product announcements and hope to see lots of comments from all our friends. We included a museum of instrumentation showing 38 years of our fluorometers in use -- please upload your photos showing our instruments in action. Under Discussions, we encourage your input on additional applications or future instrumentation you’d like us to provide. Please find us on Facebook t ...
The PhytoFlash is the first solid state (patent pending) in situ variable fluorescence system that will detect the quantum efficiency of phytoplankton in both oligotrophic and mesotrophic environments.
Unlike other active fluorometers, researchers can determine real-time in situ physiological parameters of phytoplankton in low chlorophyll systems at a fraction of the price. PhytoFlash's increas ...
