What is traceability?

Most countries hold reference standards (i.e. that nations reference for the volt; the amp, the second, etc.), normally maintained by a national standards body. National standards bodies around the world cooperate to set fundamental reference standards.

An instrument calibration is said to be traceable when the original reference sources for its calibration can be traced back to the National Reference Standards. For practical reasons this will normally be via a chain of calibrations, creating an unbroken hierarchy from the National Reference Standard through a laboratory. Primary Standard to its Working Standards (those test equipments used for commercial calibrations).

ANSI/NCSL Z540-1-1994 defines traceability as "The property of a result of a measurement whereby it can be related to appropriate standards, generally national or international standards, through an unbroken chain of comparisons".

If a measurement instrument calibration is not traceable to recognized national standards, measurements made with it may not be considered valid ... and Quality Systems, such as ISO 9000 demand that you must "identify all inspection, measuring and test equipment that can affect product quality, and calibrate them at prescribed intervals, or prior to use, against certified equipment having a known valid relationship to internationally or nationally recognized standards"

What can I expect when I send my equipment in for service?

Whether you send your item in for repair, calibration or both, we treat each unit with individual care and concern. Our process involves an eight step quality service cycle that immediately begins when your unit is delivered to our warehouse and continues until it reaches the customer.
