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.
NIRS Standard ISO 12099 â setting new performance standards for feed calibrations? April 15th, 2013 The NIRS standard ISO 12099 is developed by more than 20 NIR specialists and users and provides guidelines for determination of constituents of animal feed by near infrared spectroscopy. ISO12099 is a general standard that focuses on the validation of calibration models with independent test sets. This standard forms the basis for quality systems or accreditation schemes when using NIR. Regarding the development of calibration, reference is made to a textbook (3).
