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|
|6136-R||Used 6136 turbidity sensor with self-cleaning wiper|| |
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.

Where and how to monitor water quality is always a challenge, particularly in complex aquatic ecosystems. The new REASON Project from a team at Clarkson University is working to demonstrate the utility of using water quality instrumentation in dams on major rivers in the Great Lakes system.
Clarkson University Professor of Biology Michael Twiss spoke with EM about the new approach their team is taking at the Moses-Saunders Power Dam across the St. Lawrence River and the benefits the development of smart infrastructure such as this might offer.
“The upper St. Lawrence River is defined as that which leaves Lake Ontario and is just upstream from the city of Montreal,” explains Dr. Twiss.Read More
As we hear more and more about algal blooms of different kinds across the United States, teams of scientists are working hard to ensure that they don't become our new normal. One project in Florida is taking a multi-disciplinary approach to the problem—including genetic analysis.
The team's work is part of a full-court press in Florida recently, making a serious push to understand what is triggering more frequent blooms. Jose Lopez, Ph.D. , of Nova Southeastern University , the primary investigator on the genetic analysis portion of the project, spoke to EM about the project and his work on it.
“This is a very good project,” explains Dr. Lopez. “We're excited about it, and it's a lesson in persistence.”
From extreme weather such as Hurricane Harvey to spills and other accidents, the Gulf Coast of Texas is no stranger to dangerous situations. This is where the data provided by the Texas Automated Buoy System ( TABS ) comes into the picture.
Among the nation's most successful and longest-running coastal ocean-observing systems at the state level, the TABS real-time oceanographic buoy system monitors currents, waves, salinity, winds, and other parameters. Dr. Anthony Knap , director of Geochemical Environmental Research Group (GERG) and a Professor of Oceanography at Texas A&;M University, spoke to EM about working with TABS.
“TABS has been running now for 24 years,” explains Dr. Knap.Read More
