Quality Assurance – Measurement Control Inspection report As a measure of guaranteeing the reliability of the measurements and analyses, the air jet sieve and all system components are checked for perfect function prior to delivery. All inspections, settings and tests are documented in a final inspection report. Because all functions and settings must be checked regularly, we also offer comprehensive service. Alpine's LS-N serves as an analysis device for quality assurance as defined in DIN EN 9001, and is therefore subject to different standards in the context of test equipment monitoring.
