Lake Lugano (Ceresio) and Lake Maggiore (Verbano) comprise a significant portion of territory in Ticino, located in southern Switzerland. They are crucial to the region’s biodiversity, society, and economy. In addition to being important for ecological and tourism purposes, the lakes provide drinking water for a significant portion of the population. Recognizing the lack of […]
Oxidation-Reduction Potential (ORP), also known as Redox Potential, is a measure of water’s ability to facilitate chemical processes that either oxidize or reduce substances within it. It indicates the presence and activity of agents that can accept or donate electrons. ORP is measured in terms of electric potential with standard units of millivolts (mV). Readings […]
pH has a complex role in water chemistry as it influences the solubility, reactivity, and potential toxicity of a wide range of elements commonly found in water.
Turbidity is the state of relative clarity or cloudiness of water. Many factors can contribute to increased turbidity. The most obvious are suspended sediments consisting of various sand, silt, clay and gravel particles. These may be introduced by soil erosion, urban runoff, bottom-dwelling aquatic creatures that stir up settled sediments, or human activities such as […]
Dissolved oxygen, often abbreviated as DO, is the amount of free oxygen molecules (O2) dissolved in water. Oxygen enters the water through atmospheric diffusion, plant photosynthesis, or aeration (either natural or man-made). DO is typically represented in measurement units as percent of air saturation (%sat) and concentration in milligrams per liter (mg/L) or parts per […]
Conductivity, often denoted as EC (electrical conductivity), is a measure of a water sample’s ability to conduct electric current. It is primarily determined by the presence of dissolved salts and other inorganic substances that ionize in water. Such substances are known as electrolytes, and they conduct electricity due to their positive and negative charges. The […]
Temperature is a physical property of water indicating its relative hotness or coldness. More specifically, it is the measure of the thermal energy produced by the vibrations of water molecules. Inputs such as solar radiation increase the kinetic energy of the molecular vibrations, thereby increasing the temperature. The Celsius scale with units of degrees Celsius […]
The CB-75-SVS Wave Buoy is a simple, compact platform that integrates the NexSens X3-SUB Submersible Data Logger and the SeaView Systems SVS-603HRi wave sensor for both water and atmospheric observations. The SVS-603HRi sensor offers accurate measurements of wave height, period, direction, and more. Two additional sensor ports on the X3-SUB allow for further real-time observations […]
The CB-75 Data Buoy is a simple, compact platform that integrates the X3-SUB Submersible Data Logger for both water and atmospheric observations. The buoy features (3) 1.5″ sensor pass-through ports, an integrated solar tower with (3) 4-watt solar panels, and a topside plate supporting a solar marine light, weather stations, and other environmental sensors. An […]
Real-Time Water Quality Measurements The YSI ProSwap Loggers are compatible with NexSens X-Series data loggers using the SDI-12 sensor interface and communication protocol. Depending on the installed sensor probes, these sensors can measure various water quality parameters selected within the YSI KOR software. A user-generated script on NexSens X-Series data loggers is able to detect, […]
