A:
The thickness range of the general purpose probe (54100-05) for this instrument is 0-2000 micrometers, using magnetic induction. The accuracy is plus or minus 1 micron up to 100 nm, and the accuracy decreases with larger ranges. Since this is a ferromagnetic technology, it will measure solid polymer films over a ferromagnetic metal substance.
