YSI IDS ProOBOD Optical BOD Probe
Features
- User-replaceable, low-maintenance sensor cap with 1-year life
- Guarded sensor - the sensor guard provides protection of the sensor tip when taking the BOD probe in and out of BOD bottles
- Self-stirring to provide representative sample and increase response times
- Free ground shipping
- Expedited repair and warranty service
- Lifetime technical support
- More
Overview
The YSI ProOBOD Optical BOD Probe is designed for use with all models of the YSI MultiLab, including the 4010-1W, 4010-2W, and 4010-3W. Optical, luminescent technology eliminates the probe warm-up period and membrane changes. The self-stirring BOD probe has a super quiet lab stirrer that helps ensure a representative sample and improves DO response times.
IDS Intelligent Digital Sensors
The IDS sensors automatically store their unique serial number and calibration data. In addition, they also digitally process the measurement signal. The sensors can be moved from instrument to instrument and maintain their calibration data and transmit this information to the new instrument.
Benefits
- 2-year warranty
- Reliable and serviceable
- Probe body tapered to fit into a standard 300 mL BOD bottle
- Extremely quiet operation
- No warm-up time required
- Self-stirring to provide a representative sample and increase response times

Three Decades of Research at Acton Lake
A multi-disciplinary team at Miami University, Ohio, has been studying the environmental change at Acton Lake for over three decades. Using three different NexSens buoys over this time, the team has an incredible archive of data that is helping build a picture of Acton’s past, present, and future. Until recently, a NexSens CB-50 buoy was used alongside other environmental monitoring at Acton Lake. In May 2025, the Miami team deployed a new XB-200 buoy , future-proofing their ongoing monitoring using real-time buoy systems. Acton Lake, a small hypereutrophic reservoir in southwest Ohio, covers 2.4km² and has a maximum depth of about 8m. The dam was built in 1956, and the lake has a large agricultural watershed.

Source Water Monitoring in Albany, New York: Tracing Water Quality throughout Tributaries
Thousands of US cities pull their drinking water from natural source waters like reservoirs, rivers, and streams, making overall watershed health a key consideration for water providers. In Albany, New York, the Albany Department of Water and Water Supply delivers drinking water to over 100,000 residents as well as monitors and manages the larger drinking water supply watershed. Hannah Doherty, Environmental Specialist at the Albany Department of Water and Water Supply , spends her days working with a small team to monitor the drinking supply and the connected water bodies. Doherty explains, “We’re the first to encounter the water that ends up being the drinking water.

Wildfire Prevention in the Sierra Nevada Region with the Yuba Watershed Institute
Though recent wildfires have sparked new conversations about wildfire management and response, groups like the Yuba Watershed Institute have been monitoring the forests and water resources of the Sierra Nevada region for decades, managing approximately 5,000 acres of land with the Bureau of Land Management (BLM) and about 7,000 acres in private land partnerships. The goal of the Institute is to work with local communities and land agencies to improve watershed and forestry management through informed practices and public outreach. The goals of the Yuba Watershed Institute are three-fold: Improve the ability of fire suppression agencies like the California Department of Forestry and Fire Protection ( CAL FIRE ) and the US Forest Service.
