Applications beyond production metrology
Common applications beyond routine manufacturing include research data capture, engineering test stands, university lab exercises, prototype measurement logging, environmental or materials-test fixtures, and industrial R&D workflows that need consistent measurement output or sensor integration.
Application notes are general examples for discovery and planning; confirm suitability, tolerances, fixtures, standards, and regulatory requirements for the specific measurement task.
