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. Authority: The collection of this information is authorized under The National Institute of Standards and Technology Act, as amended, 15 U.S.C. Place the NIST reference thermometer in the water bath at the same time, to the same depth, as the bimetal coil thermometer. Choose 76 mm, 95 mm, or total immersion models. You cannot have a thermometer which is â€�traceable to NIST’. 2. They are filled with a black environmentally safe, biodegradable liquid and have a yellow back glass to create the highest contrast combination for ease of readability and prevention of reading errors. ScienceDaily. Standard Platinum Resistance Thermometer (SPRT), considered by NIST and other national laboratories to be a defining instrument for the ITS-90. 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. 5701-5709 and 5721-5739, 28 U.S.C. (NIST-certified or guaranteed by manufacturer to meet NIST standards.) It … Please see NIST Traceability for more information. NIST Calibrated Thermometers are packed in a deluxe storage box and provided with a laminated calibration report.
