Due to NIST’s current limited operational status, some calibration services may not be presently available or may experience unusual delays. calibration program. EQUIPMENT CALIBRATION . The certified thermometers are carefully inspected to insure they conform to exact specifications and are certified against NlST standards. All Traceable digital thermometers are provided with a Traceable Calibration Certificate from our ISO 17025 calibration laboratory and ISO 17034 Certified Reference Material Producer. Single & Dual Probe models. View Cart. The advan-tage is that the factory can accurately recalibrate the pyrometer in a blackbody calibrator traceable to a NIST standard. 1. Thermco’s Certified Thermometers are used in temperature verification and calibration procedures. 3. #1051-52-0) is Calibration Procedure Used: TRACEABILITY INFORMATION Date calibration reviewed: Mean Serial Number of NIST traceable thermometer: Instrument Calibrated: Serial Number: All results are reported in g/210 L Laboratory Address: Laboratory Name: This calibration is traceable to NIST through an unbroken chain of comparisons. This provides the user an opportunity to ensure that the instrument was reading accurately, and within specification, while it was in use. 5.1 Calibration Procedure 5.1.1 The thermometer for calibration shall be mercury in glass type. As found and as left data recorded at both points. References: CLSI GP31-A, Laboratory Instrument Implementation, Verification, and Maintenance; Approved Guideline, April 2009 . 65°C) to achieve accurate oven temperatures over the full range of oven operating temperatures (ambient + 5 to 99°C). 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. 4. 2019 • Conformity Assessment criteria added to checklists and to example certificate (was already in the text of procedure). United States. 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. Thermo-hygrometers have different types of sensors, but regardless of its sensor types, the procedure in calibrating them is mostly the same. 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. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-Traceable calibration. 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. NIST is committed to the health and safety of our employees and the American public and is supporting social distancing efforts. See Details. Thermometer readings are compared against NIST standards in high precision calibration baths using the comparison method at determined test temperatures. When employing thermometer calibration by the Comparison Method, readings from a thermometer with unknown accuracy are compared to those from a standard device. 2.1 Associated materials and equipment If the infrared thermometer has a reflected temperature setting, it should be set to the radia-tion source’s reflected temperature. NIST Traceable Includes Certificate of Accuracy Includes Insertion Probe. couple of hours for temperature uniformity using the NIST certi-fied thermometer—it may be necessary to let the bath equilibrate overnight. NCSLPH “Thermometer Calibration Procedure”, 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 resistance change is not generally as … ACS Calibration offers laboratory and on-site Thermometer Calibration Services..

FREE SHIPPING on all orders! OC/EC Analyzer Temperature Calibration Revision No: 5 Date: February 13, 2009 Page 2 of 13 . The reflected temperature setting may be called background For greater than 25°C temperature calibration… … IV. SOP 2 Applying Air Buoyancy Corrections 2016 NIST-traceable thermometer (digital thermometer in plastic case) Ice: check the bottom shelf of the freezer. Mercury thermometer All of the electronic temperature sensors you will be checking (YSI’s, Hydrolabs, etc.) 1) can be maintained in an instru-ment shop for calibration. • Stores thermometer calibration routines including temperature set-points, calibration distance, emissivity setting, and use of external aperture A superior target • 152 mm (6 in) diameter target addresses critical size-of-source effect issues for infrared thermometers and thermal imager calibration … Essentially, it is the condition of the device “as found” when arriving to our facility for calibration. A calibration report is generated detailing the pertinent information including the correction factors for each test point. This method can be applied for the hygrometer calibration procedure. A quality assurance system in place to maintain that measurement uncertainty. Black body calibrator Commercially available black body calibra-tors (Fig. The Facility Manager or designee may perform the annual certification of thermometers and hygrometers.
