Any Quality ruler should have high precision calibration and come with an individual certificate of Calibration. The National Institute of Standards and Technology also known as the NIST is the organization responsible for creating the standards of measurement science.
The NIST is a measurement standards laboratory. They are responsible for developing and maintaining national standards of measurement quantities. The NIST's measuring division promotes uniformity in U.S. weights and measures law and standards to achieve equity between buyers and sellers in the marketplace. This strengthens consumer confidence, and allows American businesses to not only compete here in the U.S. but overseas as well. NIST Calibration Services help customers achieve the highest measurement quality and productivity.
That is why it is always important to order certified rulers. Shlenker enterprises provides only rulers of the highest quality. They come with an individual certificate of calibration issued by an independent accredited laboratory, traceable to NIST.
To improve the quality of the calibration and have the results accepted by outside organizations it is desirable for the calibration and subsequent measurements to be "traceable" to the internationally defined measurement units. A calibration technician is entrusted with the entire process and signs the calibration certificate, which documents the completion of a successful calibration. There are many things to look for on a calibration certificate. You should check the suppliers contact details. Look for a tracking or certificate number. This is the supplier's key to all their records and a crucial aspect of traceability. The test location and date and also the conditions under which the test was completed.
