Options + NIST Calibration Certificate Order Code: /C - NIST (National Institute of Standards and Technology) Certification of Calibration states that the pressure gauge was tested at multiple test points and is within its stated tolerance of accuracy. Gauge is shipped with a sticker on the side of the gauge noting the certification number and date, and NIST certificate. Dual Scale Dials US Gauge offers most pressure ranges in dual scale, such as psi & kPa, psi & BAR, psi & kg/cm2, or single scale metric such as kPa, kg/cm2, or BAR.
Last month, we took a look at the difference between ISO 17025 accreditation and ISO 9001 certification, and weighed which one was more important. Today, weâre going to explore another set of certifications: ISO 17025 and certification from the National Institute of Standards and Technology, otherwise known as NIST. Letâs take a look at the difference between the two. NIST. We can trace the roots of NIST to the early days of the United States. For decades, an arm of the U.S. Department of the Treasury called the Office of Standard Weights and Measures oversaw, as the name suggests, weights and measures.
