The NexSens NX260 Turbidity Sensor is an optical, self-cleaning sensor designed to measure turbidity in lakes, rivers, bays, and other freshwater or marine environments. The probe is ideal for construction sites, dredging projects, stormwater applications, and many other water quality monitoring settings where water clarity is a concern.
The sensor emits light that scatters off suspended particles in the water, and the reflected intensity is measured by a photodetector at 90 degrees. An internal microprocessor applies calibration coefficients and outputs turbidity measurements in FNU. The integrated wiper cleans the optical lens prior to each measurement, ensuring accurate readings and reducing maintenance requirements.
The sensor is housed in a corrosion-resistant titanium body with marine-rated connector and scratch-resistant sapphire lens. No wiring or programming is required to integrate the sensor with NexSens X-Series data loggers. Connection to other data loggers is available using RS-485 Modbus-RTU protocol or SDI-12 with an optional converter. NexSens CONNECT software is used for configuration, calibration, and sensor verification.

Wildfire Prevention in the Sierra Nevada Region with the Yuba Watershed Institute
Though recent wildfires have sparked new conversations about wildfire management and response, groups like the Yuba Watershed Institute have been monitoring the forests and water resources of the Sierra Nevada region for decades, managing approximately 5,000 acres of land with the Bureau of Land Management (BLM) and about 7,000 acres in private land partnerships. The goal of the Institute is to work with local communities and land agencies to improve watershed and forestry management through informed practices and public outreach. The goals of the Yuba Watershed Institute are three-fold: Improve the ability of fire suppression agencies like the California Department of Forestry and Fire Protection ( CAL FIRE ) and the US Forest Service.

Wave Sensors Integration with NexSens Buoys: A Cutting-Edge Solution for Wave Measurment
Real-time wave data supports accurate weather prediction, safe and efficient maritime operations, and provides valuable safety and operating condition information for recreation and commercial fishing. Understanding wave dynamics also helps with the design of protective coastal structures like seawalls, breakwaters, and jetties. It also supports better prediction of their impact on sediment transport and coastal geomorphology. Wave data is a key factor in qualifying and designing offshore wind farms and harnessing kinetic energy for electrical generation. It helps with the understanding of ocean-atmosphere interactions and contributes to studies of sea-level rise and climate change impacts.
