Questions & Answers

| Ask a Question
How does the dissolved oxygen meter automatically compensate for pressure and salinity?
The pressure is entered as the approximate local altitude (in feet) when calibrating in % air saturation. Salinity values are manually input and can be changed without needing to recalibrate the instrument.
How do I save my measurement data?
The YSI 550A dissolved oxygen meter does not have an internal memory to store readings. This data will need to be recorded elsewhere.
What is the T95 response time?
The T95 response time is 9 seconds.

Wisconsin watershed program involves high schools to collect, share data

A group of high schoolers in the Green Bay, Wisc. area are learning about careers in environmental science thanks to the Lower Fox River Watershed Monitoring Program . The program, supported by the University of Wisconsin, has involved more than 700 students since its 2003 launch. “We have almost ten years of data,” said Annette Pelegrin, program coordinator. “It began in 2003 with five watersheds. We’ve trained teachers and schools that are interested and showed them how to measure different parameters.” Those include flow, temperature, transparency and turbidity of the program’s streams. YSI 55 meters are used to measure dissolved oxygen and levels of phosphorus, ammonia and nitrogen are checked with a Hach colorimeter. Populations of local frog and bird species are also tracked.

Colorado River Fish Contain Levels Of Selenium, Mercury

Largely seen as pristine and relatively untouched by human activity thanks to its protected status, the portion of the Colorado River flowing through Grand Canyon National Park is anything but, according to recently published research. This is evidenced by high levels of selenium and mercury found in the fishes there. Scientists from many institutions were involved in the years-long work, full results of which have been published in the journal Environmental Toxicology and Chemistry. It was led by the U.S. Geological Survey, but perhaps the contributors from Idaho State University got the best end of the stick. They were looking into the food webs of the river to evaluate concentrations of selenium and mercury gathering in fish.

Heron dipper-Tough Is Ready For Harsh Deployments

For all the straightforward groundwater monitoring applications that the folks at Heron Instruments help with, there are a few that are far from typical. These include projects that take place near remediation sites or not far from waste disposal operations. Realizing that customers working in those sorts of projects are in need of a more robust option, the company has released the dipper-Tough . The new water level meter takes inspiration from Heron’s popular dipper-T , while throwing in a host of improvements that environmental pros working in groundwater can really appreciate.
