When employing thermometer calibration by the Comparison Method, readings from a thermometer with unknown accuracy are compared to those from a standard device. This is a step-by-step procedure for calibrating the sample oven thermocouple of a carbon 2. SOP 1 Preparation of Calibration Certificates • 2018 Updated entire SOP based on changes to ISO/IEC 17025:2017, Section 7.8. calibration program. Thermo-hygrometers have different types of sensors, but regardless of its sensor types, the procedure in calibrating them is mostly the same. NIST-traceable thermometer (digital thermometer in plastic case) Ice: check the bottom shelf of the freezer. NOTE: Calibration need only be performed at a single temperature (e.g. Digital Thermometer Calibration Thermometer basics: ... For example, if the NIST thermometer reads the boiling point at 212°F and the test thermometer reads the boiling point at 210°F, all high-range temperature readings using the test thermometer would be adjusted up by 2°F.

FREE SHIPPING on all orders! NCSLPH “Thermometer Calibration Procedure”, Thermometer calibration for use in cold process and products (ice water method) A similar calibration procedure can be used for thermometers intended to be used in cold processes and products. The advan-tage is that the factory can accurately recalibrate the pyrometer in a blackbody calibrator traceable to a NIST standard. Essentially, it is the condition of the device “as found” when arriving to our facility for calibration. OC/EC Analyzer Temperature Calibration Revision No: 5 Date: February 13, 2009 Page 2 of 13 . A quality assurance system in place to maintain that measurement uncertainty. With NIST traceable calibration, any measurements taken with a certified thermometer will have: An unbroken chain of measurements that leads back to NIST maintained standards. NIST Traceable Includes Certificate of Accuracy Includes Insertion Probe. The same NIST reference thermometer used for high temperature calibration can be used for low temperature calibration as long as the thermometer is This provides the user an opportunity to ensure that the instrument was reading accurately, and within specification, while it was in use.

A calibration report is generated detailing the pertinent information including the correction factors for each test point. This calibration fulfills the requirements of ISO/IEC 17025-2005, 'General Requirements for the Competence of View Cart. Since the earlier editions (1995, 2005, 2012) numerous practical questions have been raised and Recommended calibration interval provided w/ calibration stickers. If the infrared thermometer has a reflected temperature setting, it should be set to the radia-tion source’s reflected temperature. The standard device is calibrated to meet the quality requirements of the National Institute of Standards and Technology (NIST) or a … IV.

The Traceable calibration label provides the original calibration date and the calibration due date; it is a constant reminder of the next required re-certification date. procedure and it outlines the limitations of this approach. Users can order one of two calibration tests from the NIST Calibration Services manual or from the NIST Calibration Services website . • Ensure the thermometer is NIST Traceable® or NIST Certified and remember, if your thermometer has bubbles or cracks that can not be fixed, it must be replaced. Each easy-to-read thermometer includes an individualized Thermometer Calibration Report stating corrections to one-tenth of the smallest division, unique report number and NIST standards used for the calibration. Thermometers that cannot be easily calibrated through direct immersion in either ice water or hot water can be calibrated by comparing readings with another calibrated thermometer. The ITS-90 and Thermometer Calibration Primary standards laboratories, such as the National Institute of Standards and Technology (NIST), use fixed-point cells to calibrate thermometers, such as standard platinum resistance thermometers (SPRTs), in accordance with the ITS-90 scale. 1.0 Scope and Application. 8.
