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. 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. 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. Many governments worldwide have banned or reduced the use of mercury thermometer. Place the NIST reference thermometer in the water bath at the same time, to the same depth, as the bimetal coil thermometer. PRIVACY ACT STATEMENT. Service for Outside Humidity: ± 2%. FEATURES: NIST Traceable; Standards for Calibration and Verification Procedures The main difference between a NIST Certified thermometer and a NIST Traceable® thermometer is the paperwork that accompanies the thermometer.
