The In-Situ RDO PRO-X uses optical technology to measure dissolved oxygen and temperature in aquatic environments. The RDO PRO-X is compatible with NexSens X-Series data loggers using SDI-12. Sensor Setup Before the sensor can be deployed, complete sensor setup by following the manufacturer’s guidelines. Connecting with X-Series Loggers Next, the RDO PRO-X will […]
The YSI ODO RTU Optical Dissolved Oxygen Sensors utilize the most advanced DO measurement technology. It is often used in aquaculture, hydroelectric, and many other monitoring applications. The sensor is compatible with NexSens X-Series data loggers via RS-485 Modbus protocol. Sensor Setup Before the logger can be deployed, it must first be calibrated and set […]
The In-Situ RDO Blue uses optical technology to measure dissolved oxygen and temperature in aquatic environments. The RDO Blue is compatible with NexSens X-Series data loggers using RS-485 Modbus protocol. Sensor Setup Before the sensor can be deployed, complete sensor setup by following the manufacturer’s guidelines. Connecting with X-Series Loggers Next, the RDO […]
Dissolved gases like oxygen, carbon dioxide, and methane are common in surface waters. They play important roles in aquatic ecosystems and impact atmospheric gas concentrations through air-surface flux dynamics. NexSens real-time monitoring systems with dissolved gas sensors can detect acute changes and study long-term cycles and processes.
Water quality monitoring in estuaries prior to the 1990s was labor-intensive and sporadic, as samples had to be collected and brought back to the laboratory to be analyzed using lengthy procedures with specialized equipment and reagents. During the late 1990s, new innovations in automated water quality sensors made it possible to take measurements directly in […]
Real-Time Water Quality Measurements The In-Situ Series of Multi-Parameter Water Quality Sondes (AquaTroll 200/400/500/600) are compatible with NexSens X-Series data loggers via the SDI-12 communication protocol and sensor interface. A user-generated script on NexSens X-Series data loggers can detect, log, and transmit all parameters output by the In-Situ sondes. Parameter data is transmitted, in real-time, […]
Multi-parameter monitoring platforms enable comprehensive environmental data collection by integrating multiple sensors into a single system. These platforms measure a variety of parameters in water, soil, and air. A multi-parameter platform might include, for example, a weather station and water quality sensors for an environmental study on the effect of local weather conditions on a […]
Syracuse, New York, is home to a number of urban creeks, ideal for monitoring the influence of human development on water resources. Syracuse University (SU) faculty, staff, and students have been monitoring the city’s waterways for over a decade, with Dr. Laura Lautz establishing a more formal program focused on collecting grab water samples from […]
Green Bay has suffered continuous influxes of pollutants and contaminants from the Fox River due to non-point source runoff in the watershed. Deterioration of the bay’s water quality extends well into the last century, and while cleanup efforts in the bay have been successful overall, continuous monitoring of the bay is important to ecosystem management. […]
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 […]
