Who is NIST and what do they do? They say it is traceable to NIST ethanol standards, but they never even document that they are certifying the concentration of ethanol. ; 5 U.S.C. Grainger's got your back. 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. An NIST SRM thermometer might test a second thermometer. Title: NIST calibration services for hydrometers Date Published: December 2018 Authors: John D Wright, Vern E Bean, Jesus Aguilera Report Number: NIST SP 250-78r1 doi: 10.6028/NIST.SP.250-78r1 Download PDF | Download Citation Place the NIST reference thermometer in the water bath at the same time, to the same depth, as the bimetal coil thermometer. NIST standards allow companies to ensure product precision against specific measurements. About this item. If all the appropriate paper work listing all stated uncertainties is filled out properly, that 2nd thermometer would have a certificate of compliance traceable to NIST Standards. The test certificate is issued with each calibrated temperature and corresponding correction factors to the nearest tenth of one scale division. 1 The NIST-certified thermometer was compared to a temperature device that was NIST-validated and deemed accurate, generally using a standard platinum resistance thermometer. The certified thermometers are carefully inspected to insure they conform to exact specifications and are certified against NlST standards. NIST researcher Dawn Cross calibrates a mercury thermometer using the icepoint of water as a reference. Each thermometer is certified against standards from the National Institute of Standards and Technology. PRIVACY ACT STATEMENT. Due to NIST’s current limited operational status, some calibration services may not be presently available or may experience unusual delays. The main difference between a NIST Certified thermometer and a NIST Traceable® thermometer is the paperwork that accompanies the thermometer. Infrared Thermometer 20:1 with Alarm and NIST Traceable Calibration from Digi-Sense at Southern Labware. 5701-5709 and 5721-5739, 28 U.S.C. Features include: Min / Max memory, Hold, Auto Shut-off with an LCD backlight for dark environments. ScienceDaily. An unbroken chain: Comparisons from the measurement result reported by a laboratory all the way back to … Checkout our huge collection of laboratory supplies, glass labwares & … 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) Thermistor Temperature Instrument - Traceable to Standards of NIST Model: TM99A-032. 272 and 275) and section 12 of the Stevenson-Wydler Technology Innovation Act of 1980, as amended, 15 U.S.C. When a NIST Certified thermometer is purchased, it has been tested for accuracy and can be used as a reference for testing other 3710a. The document presumes that the thermometer was originally calibrated by the manufacturer or a competent laboratory. FEATURES: NIST Traceable; Standards for Calibration and Verification Procedures 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. Authority: The collection of this information is authorized under The National Institute of Standards and Technology Act, as amended, 15 U.S.C. Distributed by the Measurement Services Division of the National Institute of Standards and Technology (NIST) Material Measurement Laboratory (MML). ... usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties. The user must decide how important the documentation is for their application. NIST Calibrated Thermometers are packed in a deluxe storage box and provided with a laminated calibration report. All temperatures correspond to the values of ITS-90. 3101-3105, … NIST (National Institute of Standards and Technology): U.S. government agency that provides standard reference materials and calibration services. QTI’s SPRT is calibrated by a nationally recognized metrology laboratory and verified by in-house TPH2O and MPGa standards.
