Thermco’s ASTM - Precision Factory Calibrated / Certiď¬�ed Thermometers are calibrated against NlST standards and comes with a calibration document showing corrections to the nearest tenth of a scale division traceable to NIST.These thermometers meet with all prescribed ASTM requirements. Choose 76 mm, 95 mm, or total immersion models. National Institute of Standards and Technology (NIST) and … An NIST SRM thermometer might test a second thermometer. A: Traceability refers to an unbroken chain of documented calibrations that have been compared to a National Institute of Standards and Technology (NIST) set standard. 2. NOTE: Thermometers should be present on all temperature‑controlled instruments and environments and checked daily. The test certificate is issued with each calibrated temperature and corresponding correction factors to the nearest tenth of one scale division. It … NIST Calibrated Thermometers are packed in a deluxe storage box and provided with a laminated calibration report. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-Traceable calibration. The linkage of a measurement back to primary temperature standards is termed metrological traceability [1]. Who is NIST and what do they do? Each thermometer is furnished with a document proving traceability and a felt-lined leatherette storage case.
