Hach Color Disc Kit
- Continuous-gradient color wheel for fast, accurate comparisons
- Accurate to +/-10% or +/- the smallest increment, subject to individual color perception
- Kits use a blank as a reference in color comparison, compensating for color in the sample
|223400||Color test kit, CO-1, 0-100 units, no limit|
|Usually ships in 3-5 days|
Simply react the sample, then insert the blank and the sample into the holder. Rotate the color wheel to obtain a color match between the blank and the reacted sample. Accuracy for color disc kits is typically +/- 10% or +/- the smallest increment, subject to individual color perception.

A happy oyster is a happy tourist: Vester Field Station’s monitoring work on the southwest Florida coast
A clean environment doesn’t just mean improved biodiversity and fresher air. It also means increased real estate demand. That fact was cemented in 2015 after a Florida Realtor’s report tied hundreds of millions of property values to the Secchi disk depth of the surrounding water.
The report was explicit about how important the environment was and how it should be treated as such.
“Policymakers and the public would benefit from research into the possible effects of Everglades restoration on water quality in the estuaries of Martin and Lee Counties,” concluded the report.Read More
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.Read More
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.Read More
