Questions & Answers

| Ask a Question
How do I calibrate my meter?
To calibrate, ensure that the sensor is disconnected from the meter. Turn the meter on and slide the O2/DO selector to the O2 position. Press the zero key to null the meter and connect the DO sensor to the top of the meter. Allow the meter to stand for at least five minutes until the display stabilizes. Press the O2 cal key and the display will indicate approx 20.9 (typical O2 in air)
Does the meter have an auto power off feature?
Yes, the meter includes an Auto Shut off feature that preserves battery life. The meter will automatically turn off after 10 minutes of inactivity.

Guardians of the Riverbank: Planting Trees to Protect Water Quality and Wildlife

In fall of 2017, the Connecticut River Conservancy (CRC) along with their project partners improved more than 9,000 feet of riverbank by planting 5,690 native trees and shrubs to protect the Connecticut River and its tributaries. The trees now guard against erosion and pollution on seven farms in New Hampshire and Vermont, and expand the existing habitat for local wildlife. This kind of project is part of CRC's core work. In August of 2011, Hurricane Irene roared up the East Coast of the United States, leaving a tell-tale path of destruction behind. Listed as the eighth-costliest hurricane in American history, the storm also hurt the watershed of the Connecticut River.

University of Toronto Doctoral Student Sees Environmental Monitoring Future in Internet of Things

Researchers face many difficulties. Assessing the ecological health of large geographic regions, especially those with a low population and few research facilities, is one of the many challenges scientists face. One such region is the Ottawa River in Canada, nearly 800 miles long with an overall drainage area of 55,000 square miles. Not only is it vast, but there are few human inhabitants and few research outposts. While gathering representative water samples in such a region is difficult enough, there is also the challenge of responding in a timely manner when problems arise.

Minnesota Water Quality Certification Program Encourages Sustainable Farming Practices

According to the Environmental Protection Agency (EPA) , agriculture is the leading probable source of impairments to assessed streams and rivers in the United States, and the third probable source to lakes. Agricultural impairments, typically considered nonpoint source pollution, include irrigation and stormwater runoff that carries animal waste, bacteria, fertilizer, naturally occurring metals, nutrients, pesticides, excess salt, and sediment. Unfortunately, this has at times positioned farmers—a group which has the most to gain from water quality initiatives—at odds with environmental agencies and scientists.
