Overview
Intellical PHC108 is a digital combination puncture pH electrode with non-refillable colored electrolyte (polymer) with a ceramic pin plus an open reference junctions, and built-in temperature sensor. The PHC108 has an easy to clean stainless steel body perfect for use in the food industries. Thanks to its spear-shaped glass sensor the PHC108 is specifically designed to measure pH in semi-solid samples.
Mechanics
The PHC108 is not suitable for use with organic solvents, low ionic strength or high alkaline sample types. IntelliCAL digital probes can be moved between meters without the need to re-calibrate or re-enter measurement settings.
Accessories Included: None
Minimum Sample Depth (mm): 15

Carbon and Nutrient Monitoring in the Great Lakes Using Satellite Observations
Carbon and nutrients are the foundation of lake food webs and play an important role in the chemical and physical processes that shape aquatic ecosystems and various lake dynamics. Studying these cornerstones can help improve understanding of other lake conditions like harmful algal blooms, hypoxia, and phytoplankton community composition. 
 
The way in which these characteristics are monitored varies, though many rely on a proxy approach wherein parameters are extrapolated from the measurement of a different parameter. An assistant professor at Cleveland State University, Brice Grunert, is working to improve current strategies and take a satellite approach to monitoring the Great Lakes.

North Texas is one of the fastest-growing regions in the state, an area that is expected to face increasing water needs. In order to meet these demands, the Upper Trinity Regional Water District ( UTRWD ) is building Lake Ralph Hall near Ladonia in southeast Fannin County, Texas. 
 
The lake has been in the works since 2003, with construction finally beginning in 2021. The population of the UTRWD is expected to grow 5-fold over the next 50 years, leading to increased water use. 
 
Ed Motley, Program Manager with the UTRWD stresses that even with conservation and reuse, new sources like Lake Ralph Hall are essential to meeting near-term and long-term water needs to support regional growth.
Read MoreScience for Science’s Sake: Monitoring Ocean Energy Availability and Gulf Stream Dynamics
Scientific research often begins with a question, sometimes driven by a specific goal or application, but many scientists believe in science for science’s sake. Marine environments and physical dynamics like the Gulf Stream are popular fields of research due to their complexity and importance, presenting a unique opportunity to learn more about previously unexplored phenomena. 
 
Environmental researchers, in particular, see the value in these ecosystems, but many also grew up with a passion for the natural world, and choosing a field that allows them to interact with and learn about the environment around us is an easy choice.
