Questions & Answers
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.
How often should the dissolved oxygen sensor be calibrated?
The DO readings should be verified before each use, and a YSI recommends performing a 1-point calibration before each use to maintain accurate readings. You can follow the instructions in the calibration guide for dissolved oxygen sensors.

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.

Lufft WS800: Introducing A Station that Can Weather the Storm

The Lufft WS800 Multi-Parameter Weather Station measures a full suite of atmospheric parameters that provides all-encompassing data on the local environment, including a one-of-a-kind lightning detector. This compact, cost-effective sensor simultaneously measures air temperature, humidity, pressure, precipitation, solar radiation, lightning, and wind with an integrated electronic compass. An internal fan and heater reduce the effects of external influences for accurate measurements during long-term deployments. The sensor can be easily mounted on a 2-inch diameter pipe above any local obstructions with the included bracket mount, U-bolts, and 10-meter cable.  Settings for the unit can be adjusted using the latest UMB-ConfigTool.

Small-Scale Monitoring for Large-Scale Impacts: Building Storm Resilience in the Newfound Lake Region

Monitoring Newfound Lake's tributaries allows the NLRA to better understand how these systems are changing and helps to quantify the impact that development is having on water quality in Newfound Lake. (Credit: NLRA) As many resource managers and conservation groups can attest, their work serves both the environment and the surrounding communities. Dynamic and healthy ecosystems can become center points for towns, cities, and entire regions—such is the case in the Newfound Lake Region, located in central New Hampshire. The  Newfound Lake Region Association  (NLRA) knows just how critical the preservation of the lake and surrounding watershed is for all members of the region.
