FEATURES: NIST Traceable; Standards for Calibration and Verification Procedures 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. Other QTI and Calibration Standards. NIST-calibrated thermometers are calibrated at NIST. The NIST thermometer works on the principle that a resonator’s natural frequency is a function of its temperature. NIST standards allow companies to ensure product precision against specific measurements. NIST Calibrated Thermometers are packed in a deluxe storage box and provided with a laminated calibration report. When a NIST Certified thermometer is purchased, it has been tested for accuracy and can be used as a reference for testing other Each thermometer is certified against standards from the National Institute of Standards and Technology. About this item. 271 et seq. Sensor experts invent supercool mini thermometer. Standard Platinum Resistance Thermometer (SPRT), considered by NIST and other national laboratories to be a defining instrument for the ITS-90. Handbook / Manual / Guide by National Institute of Standards and Technology, 10/01/1997. (which includes Title 15 U.S.C. 2,3 The certified thermometers are carefully inspected to insure they conform to exact specifications and are certified against NlST standards. ... usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties. Each thermometer is furnished with a document proving traceability and a felt-lined leatherette storage case. Infrared Thermometer 20:1 with Alarm and NIST Traceable Calibration from Digi-Sense at Southern Labware. thermometer to be calibrated in the hot water bath. The ASTM number refers to a thermometer's specific application. Traceability to the standards maintained by NIST consists of: • The linkage of a measurement back to primary temperature standards is termed metrological traceability [1]. 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. The thermometer measures changes in frequency, as measured by electronics, then maps those changes to a temperature. Choose 76 mm, 95 mm, or total immersion models. QTI’s SPRT is calibrated by a nationally recognized metrology laboratory and verified by in-house TPH2O and MPGa standards. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-Traceable calibration. 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.

Checkout our huge collection of laboratory supplies, glass labwares & … 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. 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. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).
