What is the quality standard that these thermocouples are built to? Do they conform to space ratings, ISO-9000, or NQA-1 ratings?

Asked by: Mcgoo
Thank you for your inquiry. All thermocouples made meet or exceed ISO10012-1, ANSI/NCSL Z540-1-1994 Standards. Our Laboratory is ISO 9000-2015 compliant.
