Guenther Report Number: NIST SP 260-126 rev 2013 doi: 10.6028/NIST.SP.260-126rev2013 Download PDF | Download Citation The ASTM number refers to a thermometer's specific application. Standard Platinum Resistance Thermometer (SPRT), considered by NIST and other national laboratories to be a defining instrument for the ITS-90. thermometer to be calibrated in the hot water bath. 272 and 275) and section 12 of the Stevenson-Wydler Technology Innovation Act of 1980, as amended, 15 U.S.C. Thermometric standard devices should be recalibrated or recertified prior to the date of expiration of the guarantee of calibration. Looking for DURAC CE, ROHS, NIST Standards Thermometer/Hygrometer (46Z325)? 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. The certified thermometers are carefully inspected to insure they conform to exact specifications and are certified against NlST standards. Many governments worldwide have banned or reduced the use of mercury thermometer. When a NIST Certified thermometer is purchased, it has been tested for accuracy and can be used as a reference for testing other Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-Traceable calibration. 3710a. Distributed by the Measurement Services Division of the National Institute of Standards and Technology (NIST) Material Measurement Laboratory (MML). Place the NIST reference thermometer in the water bath at the same time, to the same depth, as the bimetal coil thermometer. An NIST SRM thermometer might test a second thermometer. 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. . Other QTI and Calibration Standards. 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 NIST-calibrated thermometers are calibrated at NIST. Traceability to the standards maintained by NIST consists of: • 271 et seq. PRIVACY ACT STATEMENT. Authority: The collection of this information is authorized under The National Institute of Standards and Technology Act, as amended, 15 U.S.C. NIST is committed to the health and safety of our employees and the American public and is supporting social distancing efforts. Grainger's got your back. The thermometer measures changes in frequency, as measured by electronics, then maps those changes to a temperature. Certified, NIST Calibrated Thermometers Easy-Read® Certified Thermometers are calibrated to NIST standards at various temperature points. 3101-3105, … The test certificate is issued with each calibrated temperature and corresponding correction factors to the nearest tenth of one scale division. They say it is traceable to NIST ethanol standards, but they never even document that they are certifying the concentration of ethanol.
