Offering a precision nitrate ISE electrode sensor with an integral self-cleaning sprayer, the HYDRA Nitrate Analyzer System from Electro-Chemical Devices, Inc. is ideal for nitrate monitoring in wastewater treatment aeration basins. The intelligent HYDRA measures the concentration of dissolved nitrate as nitrogen (NO3–N) in water. The sensor uses two electrodes to determine the NO3–N concentration: a nitrate ion electrode and a chloride ion electrode. An optional electrode is also available for pH or ammonium measurement. The nitrate sensor offers 1.25-inch (31.75-mm) NPT rear-facing threads for attaching an extension/immersion tube for easy installation from catwalks or handrails. Internal signal conditioning allows the sensor to be mounted up to 200 meters (656 feet) from the analyzer. http://www.ecdi.com sales@ecdi.com
