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.

New Technologies Reducing Uncertainty in Estimation of River Flow
Some of the most interesting data in the world of river and stream monitoring come at times when it's practically impossible to capture—during extreme weather events, for example. Timing alone makes capturing unusual events a challenge, and these kinds of issues have prompted researchers to use classic monitoring data along with new technologies to develop and improve hydraulic modeling for estimating river flows. Steven Lyon , a Conservation Scientist with The Nature Conservancy, Professor at Stockholm University and Associate Professor at The Ohio State University, spoke with EM about the research .
