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|
|6150-R||Used 6150 ROX optical dissolved oxygen sensor with self-cleaning wiper|
|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.

For most humans, mayflies seem like a nuisance, hovering over the waterways as we try to enjoy them. However, for anyone hoping to monitor the health of watersheds, mayflies are important aquatic species—and now, a digital version of the mayfly is helping some scientists keep an eye on the water. Research scientist Dr. Scott Ensign , who serves as Assistant Director of the Stroud Water Research Center , spoke to EM about how the digital mayfly technology developed.
“ Shannon Hicks is the engineer who started developing the Mayfly six or seven years ago,” explains Dr. Ensign.Read More
Time is of the essence when it comes to tracking algal blooms, and people everywhere are looking for solutions. In Florida, scientists from Florida Atlantic University Harbor Branch Oceanographic Institute (HBOI) recently trialed a solar-powered, algae-tracking sail boat developed by Navocean , Inc. Dr. Jordon Beckler of Florida Atlantic University (FAU) directs HBOI's Geochemistry and Geochemical Sensing Lab and spoke to EM about the trials and the boat.
"This boat is so amazing when you see it in action," remarks Dr. Beckler. "Navocean originally contacted me a few years back about a demonstration when I was over at my previous institution in West Florida, and we brainstormed some scenarios for employing the boat for harmful algae bloom monitoring.Read More
CICHAZ Biological Field Station Provides A Unique Educational and Research Experience in Mexico’s Huasteca Region
The story of the Centro de Investigaciones Científicas de las Huastecas "Aguazarca" (CICHAZ) Biological Field Station, a member of the Organization of Biological Field Stations ( OBFS ), starts with Dr. Gil Rosenthal, Professor of Biology and Chair of Ecology and Evolutionary Biology at Texas A &; M University . Rosenthal has worked in the Huasteca region of Mexico since 1994 and for years kept his research equipment at a local ranch/hotel with the dream of one day having a field station where he could run experiments with collaborators and students. Since 2005, Rosenthal has been the Co-Director of the field station along with his wife, Dr.Read More
