Air & Water Quality Monitoring
Quality of life begins with quality of essential resources. Air and water quality monitoring can provide insights that empower communities to enhance and sustain the environment, as well as improve human health. Air quality monitoring identifies fine particulate matter and other criteria pollutants that can cause respiratory issues or worsen other health conditions. Water quality monitoring identifies contaminants to help reduce pollution and ensure that public water supplies are safe to drink.
Analog Devices, Inc. (ADI) is pushing the boundaries of performance in advanced analytical instruments used for air and water quality testing. For example, our ultraprecision converters enable 10× greater resolution in measurements of fine particulate matter to better prevent adverse effects of trace pollutants on human and planetary health.
With a broad portfolio spanning precision amplifiers, ADCs, DACs, and more, ADI’s precision and power technologies enable high sensitivity, high accuracy, repeatability, and faster throughput. We combine highly integrated analog front ends with digital back ends to offer the ultimate configurability, enabling smaller form factors, wider operating temperature ranges, reduced processing loads on CPUs and FPGAs in testing equipment, and enhanced functionality to expand sensing networks in air and water quality testing applications.
WATER QUALITY MONITORING
Water quality monitoring is crucial to reducing pollution in rivers and oceans from rapid industrial expansion. Regular testing also helps ensure drinking water quality by detecting pathogens and contaminants that may harm the population.
