The Extech Water Quality Meter Kit measures chlorine, pH, ORP, and temperature with interchangeable flat surface electrodes. The electrodes work in liquids, semi-solids, and solids. The kit includes a CL200 chlorine meter, pH and ORP electrodes, reagent tablets, 4 plastic cups, weighted stand, pH buffer pouches, batteries, and carrying case.


The memory stores and recalls up to 15 readings and saves the last calibrated value. Chlorine and ORP have an automatic electronic self-calibration, and pH calibrates to 1, 2, or 3 point buffer calibration. The smart chip predicts pH electrode performance with the "RENEW" indicator when replacement is needed, and the "CAL" indicator alerts users to recalibrate the pH electrode. Direct reading ofr total chlorine from low detection limit is unaffected by sample color or turbidity. The large 3-1/2 digit (2000) count digital display simultaneously displays ppm, pH and °C/°F temperature. Meter functions include data hold, automatic shut-off, and low battery indication.

Environmental DNA from Watersheds Could Be a New Tool in Monitoring Feral Pigs

When pigs get out of their pens, they can really tear up a landscape. Five million pigs in 39 states can tear up a lot of landscape. “They’re one of the top 100 invasive species in the world. Anywhere wild pigs are not natural and they show up, they do a lot of damage to other species,” said Dwayne Etter, a research specialist with Michigan’s Department of Natural Resources and a part of a research team that tested a new feral swine monitoring technique that uses environmental DNA. Environmental DNA (eDNA) is genetic material organisms lose in the environment. If a pig crosses a creek or defecates in it, a researcher, in theory, should be able to pull that DNA out of the water further downstream.

Birds, Fish and Shifting Sediment; How Lake Erie Buoys Measure It All

Since its population bottomed out, the federally-endangered Piping Plover in the Great Lakes has made a comeback for the ages.  A population that once measured approximately 17 pairs and rebounded, hitting 76 pairs in 2017. The same year that count was made, the plovers had also returned to Gull Point, a nesting location that hadn’t been used in more than 60 years.   In an effort to understand some of the conditions that have allowed this species to return to its habitat, researchers have directed their attention toward a curious instrument for help. A buoy that floats off the coast of Presque Isle State Park , near where Gull Point is located.

Much remains unknown about sharks. The Cal State Shark Lab wants to change that

Thirty years ago, white shark sightings near California’s beaches almost never happened. For Chris Lowe, who was a graduate student at California State University’s Shark Lab at the time, spying a dorsal fin from one of the ocean’s top predators was very rare. Prior to the mid-90’s, an expansive commercial fishing operation and the loss of marine animals decimated white shark populations. If their food wasn’t being hunted, sharks were getting caught in gill nets. At that point, they would be killed anyways before getting brought to the market to be sold. Then in 1994, California residents approved propositions that banned gillnets in state waters and enacted protections for the white shark.
