Choosing The Right Thermo Portable For Your Project
With so many options in Thermo Scientific’s Orion Star A line, it can be difficult to narrow down which meter will best fulfill a project’s needs. One easy way to rule out some meters is by considering application type. For projects that rely largely on collecting samples in the field, a portable meter is clearly the way to go. But there’s still a handful of meters to choose from. To simplify making the right choice, we spoke with Ricki Hartwell, the global product manager for Thermo Scientific’s Orion Laboratory and Field Instruments. She recently shared her tips on choosing the right Thermo benchtop . Let’s take a look at her recommendations for selecting the right portable meter.

What is Conductivity?
UPDATE : Fondriest Environmental is offering their expertise in conductivity through their new online knowledge base. This resource provides an updated and comprehensive look at conductivity and why it is important to water quality. To learn more, check out: Conductivity, Salinity and TDS . Salinity and conductivity measure the water's ability to conduct electricity, which provides a measure of what is dissolved in water. In the SWMP data, a higher conductivity value indicates that there are more chemicals dissolved in the water. Conductivity measures the water's ability to conduct electricity. It is the opposite of resistance. Pure, distilled water is a poor conductor of electricity.

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.
