XRF analyzer (lead paint testing)
Also called: XRF · X-ray fluorescence
A handheld X-ray fluorescence instrument that measures lead in paint through the layers, without scraping off samples, during a lead inspection.
What it means
A certified inspector holds the XRF against painted surfaces throughout the home to find where lead-based paint is. It's faster and less damaging than cutting out paint chips for a lab.
Why it matters in an audit
An XRF inspection tells you which windows, doors and trim contain lead before replacement or other upgrades disturb them.
