What is the unit of measurement for the XRF lead-based paint analyzer?
Due to the ability of the XRF to scan through many layers of paint, the thickness of the paint does not affect the measurement. Since the thickness can vary by a factor of 30 or more, the unit of measurement can not include depth or thickness. Thereforea weight per area measurement is used and with the SI metric convention the unit of measurement is mg/cm2.
