Overview
The ProDSS turbidity sensor is a digital smart sensor featuring welded titanium construction for use with the ProDIGITAL family of instruments. Compatible instruments include the ProDSS Meter, ProSwap Meter, and ProSwap Logger.

Mechanics
Turbidity is the indirect measurement of the suspended solid concentration in water and is typically determined by shining a light beam into the sample solution and then measuring the light that is scattered off of the particles which are present. The suspended solid concentration is an important water quality factor and is a fundamental measure of environmental change. The source of the suspended solids varies in nature (examples include silt, clay, sand, algae and organic matter), but all particles will impact the light transmittance and result in a turbidity signal.

Customizable
The ProDSS Turbidity sensor employs a near-infrared light source and detects scattering at 90 degrees of the incident light beam. According to ASTM D7315 method, this type of turbidity sensor has been characterized as a nephelometric near-IR turbidimeter, non-ratiometric. This method calls for this sensor type to report values in formazin nephelometric units (FNU). FNU is the default calibration unit for the ProDSS sensor, but users are able to change calibration units to nephelometric turbidity units (NTU), raw sensor signal (RAW), or total suspended solids (TSS).

Questions & Answers
Do I need to have a conductivity and temperature sensor installed on the ProDSS for other sensors to take accurate measurements?
There are only two parameters/sensors that do not need to be installed with a temperature/conductivity probe, turbidity and TSS. The other parameters require temperature compensation for accurate measurements.

Lufft WS800: Introducing A Station that Can Weather the Storm

The Lufft WS800 Multi-Parameter Weather Station measures a full suite of atmospheric parameters that provides all-encompassing data on the local environment, including a one-of-a-kind lightning detector. This compact, cost-effective sensor simultaneously measures air temperature, humidity, pressure, precipitation, solar radiation, lightning, and wind with an integrated electronic compass. An internal fan and heater reduce the effects of external influences for accurate measurements during long-term deployments. The sensor can be easily mounted on a 2-inch diameter pipe above any local obstructions with the included bracket mount, U-bolts, and 10-meter cable.  Settings for the unit can be adjusted using the latest UMB-ConfigTool.

Small-Scale Monitoring for Large-Scale Impacts: Building Storm Resilience in the Newfound Lake Region

Monitoring Newfound Lake's tributaries allows the NLRA to better understand how these systems are changing and helps to quantify the impact that development is having on water quality in Newfound Lake. (Credit: NLRA) As many resource managers and conservation groups can attest, their work serves both the environment and the surrounding communities. Dynamic and healthy ecosystems can become center points for towns, cities, and entire regions—such is the case in the Newfound Lake Region, located in central New Hampshire. The  Newfound Lake Region Association  (NLRA) knows just how critical the preservation of the lake and surrounding watershed is for all members of the region.

Going, Going, Gone: Endangered Species Recovery and Conservation

Across the planet, biodiversity and natural habitats are declining dramatically. Countless species of flora and fauna around the world are being listed as either threatened, endangered, or extinct. According to a 2019 UN Study , around one million species are already at risk of extinction. Unless action is taken to reduce the causes of biodiversity loss, many of these species could disappear within the next few decades. Invasive species, habitat destruction, pollution, and other environmental stressors are all major causes of biodiversity decline. While high biodiversity is synonymous with places like the Amazon Rainforest and the Great Barrier Reef, it can also be found locally.
