PONSEL's 4-electrode conductivity sensor uses 2 graphite and 2 platinum electrodes to measure specific conductivity, salinity and total dissolved solids. For specific conductivity, this sensor is within 1% accuracy for ranges as small as 0-200.0 uS/cm or as great as 0-200.0 mS/cm. The PONSEL 4-electrode conductivity sensor can measure salinity levels between 0 and 60 g/L while maintaining 0.5% accuracy.

This smart sensor can record its configuration settings and calibration history for future use without needing to calibrate. In addition, the sensor uses a digital output (Modbus RS-485 or SDI-12) for interfacing with external data loggers and meters.

When monitoring or sampling with Isco samplers, a simple cable adaptor allows the PONSEL 4-electrode conductivity sensor to interface directly with the sampler and trigger the sample when conductivity exceeds a pre-defined threshold. It can even be connected to a PC for calibration and viewing data using the CALSENS software and USB adaptor.

Data Buoys Study Turbid Water Environments in Lake Erie Basin

What started as a study into a relatively unexamined type of cyanobacteria has turned biologists from Bowling Green State University into an integral part of the effort to monitor and protect the drinking water in Sandusky, Ohio. Dr. George Bullerjahn, the Professor of Research Excellence at Bowling Green State University, has done considerable work in the study of beneficial cyanobacterial organisms in the eastern and central basins of Lake Erie. His current project is focused on the growth of the toxic cyanobacterium Planktothrix in Sandusky Bay. Over the course of his career Bullerjahn has collaborated with Dr. Steven Wilhelm from the University of Tennessee.

Bottom Composition Matters, Underwater Cameras Can Help

As a pro angler, I use my Lowrance electronics every single time I am on the water. They are great at locating fish and structure, but when combined with my FishSens SondeCAM HD Underwater Camera they can show everything. A camera is a great tool for someone who wants to better understand what they are seeing on their electronics and for me, it helps get a clear picture of one of the most important things in bass fishing: bottom composition. Hard Spots Hard bottoms are usually the best, and bass will relate to hard bottoms of different types depending on the region. My Lowrance StructureScan will show hard bottoms as bright, white areas on the screen where softer bottoms will be more grayish.

Targeting Spawning Bass: Are They Going to Bite?

This time of year, anglers all over are fishing for bass they can see in the shallows. Some bass will be easy to catch and some are nearly impossible, like those that are in the act of spawning instead of just guarding their beds. There are a few things that I do to determine if the fish is going to bite and if they are worth spending time fishing for. Locating Bedding Bass One of the best ways to find bedding bass is to cruise the shallows with your trolling motor at about 40 or 50%. I have found that this is the best speed to both cover water and avoid spooking fish. Anything faster will scare fish away long before you get to them.
