I'm interested in exploring the best available dissolved oxygen sensors specifically designed for wastewater applications, particularly those that can accurately measure within the range of 0 to 40 mg/L. It's crucial that the sensor provides reliable and precise readings under typical wastewater conditions. Please provide me with detailed information about your top products in this area, focusing on their features, accuracy, and any unique technologies that set them apart from competitors. Additionally, I'd like to know about the durability and maintenance requirements of the sensors you recommend. Understanding the installation process and any additional accessories that might be needed would also be helpful. If there are options available for different budgets or specific technical needs, please include that information as well. I'm looking forward to your insights and suggestions on the best solutions for my wastewater monitoring needs.
