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 […]
Hydropower plants are important for energy generation, but their presence dramatically changes the surrounding landscape. There are also many factors which affect plant operation and maintenance. NexSens comprehensive monitoring systems can be implemented at hydropower assets both to reduce environmental impact and optimize operations.
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.
Real-Time Water Quality Measurements The YSI ODO RTU Optical Dissolved Oxygen Sensor is compatible with NexSens X-Series data loggers using the Modbus-RTU communication protocol and the RS-485 sensor interface. A pre-defined script on the X-Series data loggers can detect, log, and transmit all parameters available on the sensor. Parameter data is transmitted, in real-time, at […]
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 using the Modbus-RTU communication protocol and RS-485 sensor interface. A pre-defined script on X-Series data loggers is able to detect, log and transmit all parameters available on all models of In-Situ sondes. Parameter data […]
Utilize the YSI ODO calibration utility to enter calibration coefficients when installing new DO sensor caps. Calibration coefficients are located on the “YSI ODO Sensor Cap Instruction Sheet” included with the new sensor cap. Once entering the coefficients, the user will need to perform a 1-point DO calibration within the utility. CONNECT will utilize the […]
Utilize the YSI ODO RTU calibration utility in CONNECT to enter calibration coefficients, and directly calibrate both dissolved oxygen and conductivity. Calibration coefficients are located on the “YSI ODO Sensor Cap Instruction Sheet” included with the new sensor cap. Once entering the coefficients, the user will need to perform a 1-point DO calibration within the […]
Real-Time Dissolved Oxygen Measurements The In-Situ RDO-Pro-X and RDO-Blue Dissolved Oxygen (DO) Sensors use In-Situ’s patented Optical Rugged Dissolved Oxygen technology, an EPA-approved DO measurement method. These sensors are compatible with NexSens X-Series data loggers via the Modbus-RTU protocol and the RS-485 sensor interface. A pre-defined script on X-Series data loggers is able to detect, […]
