Description
This 17-7PH certified reference material is a precipitation-hardening stainless steel alloy used as a standard for calibrating and verifying your spectrometer (handheld XRF, benchtop XRF, Handheld LIBS, and Spark OES). This material is certified with values established through interlaboratory testing, giving you traceable, defensible composition data for calibration checks, instrument verification, and quality control on high-strength aerospace-grade stainless steel.
For field verification and PMI work, many customers pair this material with NEW or PRE-OWNED handheld XRF analyzers for rapid, on-site analysis.
