PhytoFlash Submersible Fluorometer

PhytoFlash Submersible Active Fluorometer

Designed in 2006, PhytoFlash has become too expensive a product to manufacture and still offer at a reasonable price so we obsoleted it effective September 1, 2018.  If you have interest in a low-cost Active Fluorometer and can use a handheld instrument, please take a look at our AquaFlash which provides accurate estimations for total chlorophyll and photosynthetic efficiency in less than 15 seconds.   We are offering PhytoFlash owners a trade-in discount toward the purchase of an AquaFlash.  To take advantage of the PhytoFlash Trade-In Program please complete our AquaFlash Handheld Active Fluorometer quotation request form and indicate the serial number of the PhytoFlash you wish to trade in.

We will continue to provide service & accessories for PhytoFlash.   Please contact us for pricing and availability.

Frequently Asked Questions

Do you have any documents that explain active fluorescence?

Turner Designs offers extensive resources for many common fluorescence applications. For specific documents regarding active fluorescence please visit our parameters page.

Do you have any information on ASCII termination characters in the integration mode?

If the user wants to exit the integration mode entirely, they may send the PhytoFlash an ASCII ESC character.

There is a nice tool available that may help answer any questions related to ASCII string characters:

This tool is a serial port monitor. It allows the user to see data in the packets that are transmitted on a serial port. In this case, the user could set up the PhytoFlash for integrated monitoring and see the actual raw data packets that are transmitted to Hyperterminal (or equivalent). Seeing the raw data would answer any questions concerning formatting. For instance, it will show that the numeric data is separated by tabs, not spaces. It will also, of course, show the termination characters for each line.

Can the PhytoFlash measure carbon fixation rates?

The PhytoFlash will not measure Carbon Fixation Rates. However, users can calculate Carbon Fixation Rates if other measurements are taken (e.g. Carbon per cell). So, measurements made outside the realm of the PhytoFlash can be used with the reading PhytoFlash gives to come up with Carbon Fixation Rates, Oxygen Evolution, etc. Suggested reading:
