3101-3105, … ScienceDaily. Each thermometer is certified against standards from the National Institute of Standards and Technology. About this item. (NIST-certified or guaranteed by manufacturer to meet NIST standards.) The document presumes that the thermometer was originally calibrated by the manufacturer or a competent laboratory. 271 et seq. Handbook / Manual / Guide by National Institute of Standards and Technology, 10/01/1997. NIST-calibrated thermometers are calibrated at NIST. All Traceable digital thermometers are provided with a Traceable Calibration Certificate from our ISO 17025 calibration laboratory and ISO 17034 Certified Reference Material Producer. All temperatures correspond to the values of ITS-90. The user must decide how important the documentation is for their application. Each thermometer is furnished with a document proving traceability and a felt-lined leatherette storage case. national3ureauofstandards instituteforbasicstandards washington,d.c.20234 reportofcalibration liquid-in-glassthermometer testedfor:nationalbureauufstandards division22l,section11 marked:surety198692 range:-2to+102degreescin0.2degree thermometer correction reading (ipts-68)**-.06c.06c 20.00.13 40.00.05 60.00 **inthe of of inisin•• of in. . ... usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties. It … NIST's superconducting thermometer measures temperatures below 1 Kelvin (minus 272.15 °C or minus 457.87 °F), down to 50 milliKelvin (mK) and potentially 5 mK. Distributed by the Measurement Services Division of the National Institute of Standards and Technology (NIST) Material Measurement Laboratory (MML). 3710a. The ASTM number refers to a thermometer's specific application. QTI’s SPRT is calibrated by a nationally recognized metrology laboratory and verified by in-house TPH2O and MPGa standards. NOTE: Thermometers should be present on all temperature‑controlled instruments and environments and checked daily. NIST is committed to the health and safety of our employees and the American public and is supporting social distancing efforts. The certified thermometers are carefully inspected to insure they conform to exact specifications and are certified against NlST standards. Service for Outside Temperature: ±1°F at -50, -15, 0, 40, 80 and 140°F (±0.5°C at -45, -26, -18, 4, 27 and 60°C) 2. NIST Handbook 105-6 Specifications & Tolerances for Reference Standards & Field Standard Weights & Measurements - 6- Specifications & Tolerances for Thermometers. Looking for DURAC CE, ROHS, NIST Standards Thermometer/Hygrometer (46Z325)? NIST traceable calibration is an assurance program that certifies that a laboratory or manufacturer is fully equipped to calibrate equipment to the National Institute of Standards and Technology (NIST) standards and that any products offered by that manufacturer will match those NIST-maintained measurement standards. Choose 76 mm, 95 mm, or total immersion models. The National Institute of Standards and Technology (NIST) is a physical sciences laboratory and a non-regulatory agency of the United States Department of Commerce.Its mission is to promote innovation and industrial competitiveness. NIST researcher Dawn Cross calibrates a mercury thermometer using the icepoint of water as a reference. An unbroken chain: Comparisons from the measurement result reported by a laboratory all the way back to … thermometer to be calibrated in the hot water bath. The thermometer measures changes in frequency, as measured by electronics, then maps those changes to a temperature. (2020, November 17). Clinical Laboratory and Standards Institute (CLSI): NIST Temperature and Humidity Group staff have worked with CLSI staff to update standards calling for the use of mercury-in-glass SRM thermometers, enabling laboratories to use other thermometer types with NIST traceability.
