Questions & Answers
How do I calibrate my meter?
To calibrate, ensure that the sensor is disconnected from the meter. Turn the meter on and slide the O2/DO selector to the O2 position. Press the zero key to null the meter and connect the DO sensor to the top of the meter. Allow the meter to stand for at least five minutes until the display stabilizes. Press the O2 cal key and the display will indicate approx 20.9 (typical O2 in air)
Does the meter have an auto power off feature?
Yes, the meter includes an Auto Shut off feature that preserves battery life. The meter will automatically turn off after 10 minutes of inactivity.

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.
