Questions & Answers
My DO% samples read low and then high to low, is this a bad reading?
The initial power up can make the first two DO% readings read low. These readings can be disregarded.
My sonde is reading a negative value for turbidity, did I calibrate incorrectly?
A sonde (even if cleaned properly) can contaminate to almost 1.0 NTU. Typically the average contaminant level ranges from 0.2 to 0.8 NTU. With this knowledge, you can enter this offset (0.5 NTU) using the sonde's One-Point Calibration feature. This calibration...

Applied Research and Innovative Solutions: Creating CHNGES at Western Kentucky University

Long-standing environmental monitoring programs have the power to support a large number of research initiatives and policy changes—however, actually starting these networks can prove challenging. Not only is starting the program difficult, but keeping things operational for decades to come has also been challenging for environmental professionals hoping to make an impact with applied research. Jason Polk, Professor of Environmental Geoscience and Director of the Center for Human GeoEnvironmental Studies (CHNGES) at Western Kentucky University, is all too familiar with this process.

Combating Water Insecurity in Saskatchewan with Real-Time Data

The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.

Seametrics Turbo Turbidity Logger: Boost your Turbidity Monitoring

The Seametrics Turbo Turbidity Logger is a self-cleaning turbidity sensor capable of internally logging over 260,000 data records. The sensor enables researchers, compliance officers, and contractors to monitor turbidity in various applications, from construction and dredging sites to wastewater effluent.  Due to its narrow width, this device can be deployed in a range of areas, from small well spaces to rivers and streams. The stainless steel housing and built-in wiper allow the sensor to withstand long-term deployments and reduce the need for maintenance trips.  The logger accurately records temperature and turbidity up to a depth of 50 meters.
