Questions & Answers

| Ask a Question
How does a Polarographic DO sensor work?
In a polarographic sensor, the cathode is gold and the anode is silver. The system is completed by a circuit in the instrument that applies a constant voltage of 0.8 volts to the probe, which polarizes the two electrodes. The sensor operates by detecting a change in this current caused by the variable pressure of oxygen while the potential is held constant at 0.8 V. The more oxygen passing through the membrane and being reduced at the cathode, the greater the signal increases.
Why is the Polarographic sensor warranted for 1 year while the Galvanic is only warranted to 6 months.
Galvanic sensors continually consume the anode, even when the instrument is off. The consumption of the polarographic sensor stops when the instrument is turned off, giving it a longer sensor life.
Is this sensor approved by the EPA?
Yes, the proven technology of the steady-state sensor is approved by the US EPA for compliance monitoring and reporting.

Mississippi Gulf Coast fish kill expected to continue

Officials at the Mississippi Department of Marine Resources say that a recent fish kill along the state’s Gulf coast is the largest they’ve seen, according to KVUE . The fish kill has brought dead crabs, eels and stingrays ashore. Beachgoers were disturbed by the large-scale kill, but experts explained that conditions this year were to blame. With higher temperatures and low dissolved oxygen near the sea floor, creatures that live there were more likely to be affected. The fish kill, beginning July 1, was the first of 2013 for the area. It was expected to last several more days, but lessen over that period.

Targeting Spawning Bass: Are They Going to Bite?

This time of year, anglers all over are fishing for bass they can see in the shallows. Some bass will be easy to catch and some are nearly impossible, like those that are in the act of spawning instead of just guarding their beds. There are a few things that I do to determine if the fish is going to bite and if they are worth spending time fishing for. Locating Bedding Bass One of the best ways to find bedding bass is to cruise the shallows with your trolling motor at about 40 or 50%. I have found that this is the best speed to both cover water and avoid spooking fish. Anything faster will scare fish away long before you get to them.

Researchers Find Link Between Climate Change and Gastrointestinal Illnesses

An understanding of climate change’s effects on the environment has become commonplace and grows every day, but one researcher from Florida State University is looking to answer a new question: What are climate change’s effects on people’s health? In one of the first studies of its kind, Chris Uejio, an assistant professor at FSU, and a team of researchers studied how climate change can affect the roughly 20 million Americans (according to the Environmental Protection Agency) who consume untreated drinking water on a daily basis. Because climate forecasts are predicting higher rainfall rates over the next few decades, coming down in intense storms, Uejio said those flashes could cause flare-ups in waterborne illnesses.
