Description
This 300M certified reference material is an ultra-high-strength low alloy steel used as a standard for calibrating and verifying your spectrometer (handheld XRF, benchtop XRF, OES). This material is certified to ISO 17034, giving you traceable, defensible composition data for calibration checks, instrument verification, and quality control on aerospace landing gear and structural-grade alloy 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.
