Overview
The Thermo Orion Star RDO optical dissolved oxygen probes have a 9 pin miniDIN connector that ensures a waterproof and secure connection when used with the Orion Star Plus RDO optical dissolved oxygen meters. The RDO sensor has an internal clock that counts down the 365-day lifespan of a new RDO cap.

Applications
The Thermo Orion RDO Optical Dissolved Oxygen Probes is compatible with a wide range of applications, including rugged field applications, water and wastewater analysis and beer and wine testing. All of the RDO sensors feature automatic temperature compensation and convenient press-on RDO caps.

Questions & Answers
How often should I change the RDO cap?
The RDO cap needs to be changed once a year. The RDO sensor has an internal clock that counts down the 365 day lifespan of the RDO cap. The countdown begins the day the cap is installed, sensor is connected to the meter, and the first measurement is taken. The meter will display an "Err 181" message when the cap needs to be replaced.
My sensor is reading a bad zero point calibration.
The sensor must be in an oxygen-free solution for at least 5 minutes.

Data-Driven Decisions: Tracking Sediment during the Klamath Dam Removal

The largest dam removal in U.S. history, the deconstruction of the Klamath Dam is slated to begin this summer. The project includes four dams along the Klamath River with the first and smallest dam, Copco #2, scheduled for removal first. As each of the dams are torn down, scientists and consultants will keep a close eye on the state of the Klamath River downstream to assess the impact of undamming the river. Shawn Hinz, managing partner and environmental toxicologist with Gravity Consulting , has been involved with the Klamath Dam project for over a decade. Hinz was a part of these earlier steps, representing the academic stakeholder position as a graduate student sitting on a board of other stakeholders.

From the Tap: Source Water Monitoring for Public Health

In regions with historically secure access to clean drinking water, few think about the work that goes into ensuring that the water they fill their cups with is safe. In reality, millions of dollars are invested in the infrastructure, equipment and teams involved in converting source water into drinking water. While all the work that goes into providing clean water often goes unnoticed, analysts like Michele Gilkerson, a water research analyst with the City of Columbus Division of Water, know exactly how much goes into securing safe water for millions of people. Gilkerson started with Battelle Memorial Institute in 1991 in their water ecology section. There, she saw how interesting source water monitoring could be, even though it isn’t often spotlighted in the environmental sector.

Choosing the Right Water Quality Monitoring Systems Is Crucial for Stantec Inc.

Data is king when it comes to water quality monitoring. It is not merely the type of data being collected that matters but also how that data is stored, processed and presented. When Joseph Kamalesh, a project manager with  Stantec Consulting Services Inc. , needs to find the right equipment for large client-based projects, he knows to keep these factors in mind. Joseph has a background in water quality and water flow monitoring instrumentation, which he continues to focus on at Stantec. During college and his early career, Joseph gained experience with water instrumentation, consisting primarily of on-site wastewater sampling and sampling small systems.
