The Thermo Orion Dissolved Oxygen BOD Probe greatly simplifies the routine measurement of dissolved oxygen, particularly biochemical oxygen demand (BOD). The polarographic electrode allows dissolved oxygen concentration to be read directly in parts per million on any pH meter, eliminating the need for a dedicated readout meter.

When used with your standard pH meter, the Orion 970899WP Oxygen electrode provides a convenient interface for measuring biochemical oxygen demand (BOD). Built-in circuits convert the output to a signal that can be read by most pH meters. Standardization is fast and easy using water-saturated air or a chemical standard. An overflow funnel for use in BOD bottles allows measurements to be made in the same bottle before and after incubation.

Maintenance is easy with the pre-assembled membrane/electrolyte module. There are no membranes to cut or solution to pour. Each Orion 970899WP is packaged complete with two membrane/electrolyte modules, overflow funnel with built-in stirring bar, and batteries.
Notable Specifications:
  • Electrode Type: Polarographic Gas Sensing Combination
  • Concentration Range: 0 to 14 ppm (nominal)
  • Accuracy: +/-0.05 ppm or 2% of reading, whichever is greater
  • Response Time: 96% response in less than 30 seconds between oxygen-free and air-saturated water at 22 C
  • Oxygen Consumption: 0.1 mg/hr

Questions & Answers

| Ask a Question
How long is the battery life?
The battery will last one year if the probe is used for approximately 4 hours a day.
After I install a new membrane, can I use the probe immediately?
After installing a new membrane, leave the probe in a BOD bottle with 50mL of distilled water for 30 minutes before calibrating.

First Environmental Monitoring System For Baltimore’s Inner Harbor

Baltimore’s Inner Harbor and the rivers that flow into it are important sources of water to Chesapeake Bay, popular recreation sites and the targets of an ambitious clean-up plan. But the city has for some time lacked an environmental monitoring system for tracking water quality in the harbor continuously. That is about to change, thanks to a collaboration between the U.S. Geological Survey (USGS) and Environmental Protection Agency (EPA). It will lead to the new installation of a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in the harbor.

Parasite Behind Yellowstone River Fish Kill Found In Other Rivers

A parasite that caused a massive fish kill in Montana’s Yellowstone River has been found in at least seven other rivers in the state, according to the Bozeman Daily Chronicle . Scientists with the Montana Fish, Wildlife and Parks department made the find. So far, the parasite has been confirmed in the upper and lower Madison, East Gallatin, Bighorn, Stillwater, and Boulder Rivers. It had already been confirmed in the Jefferson and Shields Rivers. The microscopic parasite causes proliferative kidney disease, one of the most serious diseases to impact whitefish and trout. The effect of the disease on Yellowstone’s fish populations is exacerbated by other stressors like near-record low flows, consistent high temperatures and the disturbance caused by recreational activities.

ESPniagara Tracks Algal Toxins In Lake Erie, Protects Drinking Water

It may have taken 20 years and $20 million to develop, but Lake Erie researchers working to fight harmful algal blooms (HABs) now have a new tool to safeguard drinking water: ESPniagara. The advanced sampler has been called a “lab in a can” for its ability to sample microcystins, the most common algal toxin these days, in almost real time. The big gadget’s name is a mashup between “ESP,” for environmental sample processor, and the name of Admiral Oliver Hazard Perry’s ship during the War of 1812. “We wanted to name it something that was significant to Lake Erie,” said Tim Davis, molecular biologist and lead HABs researcher at the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Lab (NOAA GLERL) in Ann Arbor, Mich.
