Used YSI 650 MDS Multi-Parameter Display
- Easy-to-use, menu-driven interface in a compact, rugged, water-proof field display
- Compatible with all YSI 6-Series Sondes
- 30 hour battery life (4 C-cell batteries)
|650-03-R||Used 650 Multi-parameter display with barometer, standard memory|
|6091-R||Used 6091 field cable, 25 ft.|
|6920V2-R||Used 6920 V2-2 Sonde with temperature/conductivity sensor|
|Usually ships in 3-5 days|
|655564||5564A amplified pH sensor|
|655565||5565A amplified pH/ORP sensor|
|Usually ships in 3-5 days|
With the standard alkaline battery configuration of 4 C-cells, the YSI 650 will power itself and a YSI 6600 sonde continuously for approximately 30 hours. Temperature-compensated barometer readings are displayed and can be used in dissolved oxygen calibration. Measurements can be logged to memory for tracking changes in barometric pressure.
Standard memory will allow for approximately 150 data sets. Exact logging capacity is dependent on the number of active parameters in the 6-series sonde. Optional high memory (1.5 MB) would make it possible to easily upload the data from 7 sondes, each of which have data files of approximately 75 days at a 15-minute sampling interval.

Each year in Germany, as many as 450,000 living fish undergo live animal experiments to test how fish-friendly hydroelectric power plants in the country are. The idea is to discover how readily the fish can move through hydroelectric turbine installations in order to ultimately reduce mortality rates.
Of course, subjecting live fish to a potentially deadly test to save others is a bitter irony. And it's one that a team of scientists from the RETERO research project hopes to eventually mitigate with a robotic fish for testing.
EM corresponded with Olivier Cleynen and Stefan Hoerner from the University of Magdeburg about the complex flow conditions that set the parameters for the project.Read More
News stories about dogs getting sick from harmful algal blooms (HABs) in lakes have caused worry among members of the public this summer more than once. But Regional Science Consortium (RSC) Executive Director Dr. Jeanette Schnars and a dedicated team are bringing awareness about HABs to the public with the Mobile HAB Lab.
“We just launched the HAB Citizen Scientists program this year,” explains Dr. Schnars. “It helps us work with people, especially people who spend time at marinas frequently, that are out there all season long.”
The season for boaters at Presque Isle, where RSC is located, starts in mid-May and usually continues through the beginning or middle of October.Read More
In the battle against harmful algal blooms (HABs), time is important . The need for laboratory equipment and testing is a serious challenge for water managers. This issue caught the eye of Qingshan Wei , an assistant professor of chemical and biomolecular engineering at North Carolina State University .
“Our research group is interested in developing low-cost sensors,” Wei told EM . “Recently we have been developing sensors for environmental monitoring, and cyanotoxins came to our attention .”
Cyanobacteria, which generate HABs, are becoming a challenge across the US . They are a very serious problem in North Carolina, in part due to the weather.Read More
