Description
This 1144A certified reference material is a resulfurized carbon steel alloy 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.
For field verification and PMI work, many customers pair this material with NEW or PRE-OWNED handheld XRF analyzers for rapid, on-site analysis.
