How Do You Guarantee an Exact Gas Concentration From a Gas Diluter?
Short answer: an exact calibration gas concentration is never a single spec on a datasheet — it’s the result of a verified chain: each Mass Flow Controller (MFC) is individually flow-calibrated against a NIST-certified reference, the diluter’s output is checked analytically against a validated analyzer, and the result is cross-checked against a certified cylinder at […]
