When tested with an XRF instrument the Kwikset door handle pictured here had the following readings:
- Lead (Pb): non-detect
- Cadmium (Cd): non-detect
- Mercury (Hg): 494 +/- 185 ppm
- Barium (Ba): non-detect
- Chromium (Cr): non-detect
- Antimony (Sb): non-dtect
- Selenium (Se): non-detect
- Zinc (zn): 168,600 +/- 1,800 ppm
All testing is done with a freshly calibrated XRF instrument. Test results are science-based and replicable. Testing was done for a minimum of 60 seconds each time (with multiple tests done to confirm the results.)
As always, thank you for reading and for sharing my posts.
