The Photoacoustic Extinctiometer is Droplet’s premier instrument for measuring aerosol optical properties.
产品描述
The PAX is a sensitive, high-resolution, fast-response instrument for measuring aerosol optical properties relevant for climate change and carbon particle sensing.
Achieve excellent scattering coefficient sensitivity with reciprocal nephelometry.Count on fast response, one-second resolutionReal-time data display on a high-resolution touch screen.Get continuous and autonomous operation, with no filter collection required and no filter data artifacts.
Get accurate measurements for both light absorption and scattering in a single instrument. Then correlate the absorption measurement black carbon mass concentration.Select from three wavelengths (870 nm [standard], optional 405 nm, or 532 nm), and get wide dynamic range suitable for pristine regions to source sampling.
Data averaging time1, 10 or 60 seconds, user selectable
Zero check On demand, or automated at user selectable interval at 5, 15, 20, 30, or 60 minutes. Zero check with high-efficiency filtered air sample.
