Certified, NIST Calibrated Thermometers Easy-Read® Certified Thermometers are calibrated to NIST standards at various temperature points. Infrared Thermometer 20:1 with Alarm and NIST Traceable Calibration from Digi-Sense at Southern Labware. Place the NIST reference thermometer in the water bath at the same time, to the same depth, as the bimetal coil thermometer. 3101-3105, … 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) Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-Traceable calibration. Where to Buy Request a Demo/More Info. 2. ; 5 U.S.C. National Institute of Standards and Technology (NIST) and … The main difference between a NIST Certified thermometer and a NIST Traceable® thermometer is the paperwork that accompanies the thermometer. An NIST SRM thermometer might test a second thermometer. NIST Calibrated Thermometers are packed in a deluxe storage box and provided with a laminated calibration report. The certified thermometers are carefully inspected to insure they conform to exact specifications and are certified against NlST standards. 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. Checkout our huge collection of laboratory supplies, glass labwares & … ScienceDaily. Researchers at the National Institute of Standards and Technology (NIST) have invented a miniature thermometer with big potential applications such as monitoring the temperature of … Grainger's got your back. Traceability to the standards maintained by NIST consists of: • You cannot have a thermometer which is â€�traceable to NIST’. The NIST thermometer works on the principle that a resonator’s natural frequency is a function of its temperature. Each thermometer includes a calibration document showing corrections; documents are fully traceable to NIST standards. ... usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties. Standard Platinum Resistance Thermometer (SPRT), considered by NIST and other national laboratories to be a defining instrument for the ITS-90. National Institute of Standards and Technology (NIST). By contrast, conventional thermometers for sub-Kelvin temperatures rely on measurements of electrical resistance. They say it is traceable to NIST ethanol standards, but they never even document that they are certifying the concentration of ethanol. Website is owned by NIST (an agency of the U.S. Department of Commerce) NIST reserves the right to charge for access to this database in the future. NOTE: Thermometers should be present on all temperature‑controlled instruments and environments and checked daily. . Key Features Thermistor Temperature Instrument - Traceable to Standards of NIST Model: TM99A-032. When a NIST Certified thermometer is purchased, it has been tested for accuracy and can be used as a reference for testing other The linkage of a measurement back to primary temperature standards is termed metrological traceability [1]. 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. Distributed by the Measurement Services Division of the National Institute of Standards and Technology (NIST) Material Measurement Laboratory (MML). Due to NIST’s current limited operational status, some calibration services may not be presently available or may experience unusual delays. 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. An unbroken chain: Comparisons from the measurement result reported by a laboratory all the way back to … The ASTM number refers to a thermometer's specific application. A truly bush league mistake. PRIVACY ACT STATEMENT. Sensor experts invent supercool mini thermometer. Who is NIST and what do they do? 271 et seq. NIST (National Institute of Standards and Technology): U.S. government agency that provides standard reference materials and calibration services. The thermometer measures changes in frequency, as measured by electronics, then maps those changes to a temperature. NIST researcher Dawn Cross calibrates a mercury thermometer using the icepoint of water as a reference. 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 Each thermometer is furnished with a document proving traceability and a felt-lined leatherette storage case. The TM99A-032 is the industry standard for applications where only one temperature is read at a time. 5701-5709 and 5721-5739, 28 U.S.C. 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. The document presumes that the thermometer was originally calibrated by the manufacturer or a competent laboratory. 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. Each thermometer is certified against standards from the National Institute of Standards and Technology. NIST standards allow companies to ensure product precision against specific measurements. Features include: Min / Max memory, Hold, Auto Shut-off with an LCD backlight for dark environments. Title: The NIST Traceable Reference Material Program for Gas Standards Date Published: February 2015 Authors: William D. Dorko, Michael E. Kelley, Franklin R. Guenther Report Number: NIST SP 260-126 rev 2013 doi: 10.6028/NIST.SP.260-126rev2013 Download PDF | Download Citation All temperatures correspond to the values of ITS-90. It … thermometer to be calibrated in the hot water bath. Handbook / Manual / Guide by National Institute of Standards and Technology, 10/01/1997. Traceable® Min/Max Total-Range Digital Alarm Thermometer, –328 to 2498°F / –200 to 1370°C with a NIST Traceable® Calibration Certificate (each) Add to compare $112.63 $132.50 The user must decide how important the documentation is for their application. 272 and 275) and section 12 of the Stevenson-Wydler Technology Innovation Act of 1980, as amended, 15 U.S.C.
