Quality control: optical measurement and XRF testing
Robo-Fit says it has invested heavily in quality control. Its automated optical inspection takes hundreds of high-precision measurements in seconds and records the data and inspection reports automatically. Robo-Fit doesn't rely only on brass mill certificates. It follows a “trust but verify” approach and checks material composition in-house with X-ray fluorescence (XRF) analysis.
