NIST-Traceable calibration for liquid-in-glass thermometers at 2 to 4 points
More About this Item
Glass thermometers are one of the most common types of temperature instruments and are available in a variety of styles, sizes, and versions. Their unique characteristics of wide range, precision, repeatability, and quick response create a unique challenge for the metrologist who is calibrating these instruments. InnoCal can calibrate spirit-in-glass (SIG) thermometers. Calibrations for glass thermometers use direct comparison in high-stability liquid baths using Precision Reference Thermometers (PRTs) and Standard Platinum Resistance Thermometers (SPRTs) and high precision displays. The glass thermometers are inspected for cracks and liquid-column separations before testing.
InnoCal is the only authorized service center for ERTCO brand liquid-in-glass (LIG) thermometers in the United States
We also calibrate any make and model of LIG thermometers including Brooklyn Thermometer, Miller and Weber, Inc., LSW, and H-B Instruments
Testing range for liquid-in-glass thermometers is from –80 to 420°C (–176 to 788°F)
Calibrated at manufacturer’s recommended points or at your desired points depending on your specific requirements. Correction factors are also provided for your convenience.
To meet your calibration needs:
All calibration certificates contain as-found and as-left data, estimated measurement uncertainties (emu’s), and test uncertainty ratios (TUR’s) at no additional cost!
This NIST-traceable calibration allows you to confirm that the specific asset you purchase meets the manufacturer’s published specification
EPA, USDA, ISO, and GLP/GMPs standards require regular NIST-Traceable calibration of all test equipment being used in critical applications
Receive your product calibrated and ready to use rather than sending it to a third-party or internal calibration lab and incurring additional delays
All measurements reported are traceable to SI units via national standards maintained by NIST and performed in compliance with ANSI Z540, ISO17025, and MIL-STD-45662A. FDA Compliant.
InnoCal is accredited to ISO/IEC 17025 by the American Association for Laboratory Accreditation (A2LA) under certificate number 1746.01. This accreditation is your assurance that the calibration is performed in a qualified, controlled laboratory.
Calibrations on glass thermometers are performed using direct comparison in high-stability liquid baths using high-precision PRT’s and SPRT’s and displays. Thermometers are inspected for cracks and liquid-column separations before testing. Measurements are performed at 2 to 4 points between -197 deg C and 550 deg C.
Points are generally selected at the manufacturer’s specified points but customer-specified points can be accommodated. For certificates with more calibrations points, see 17006-05 for 5 to 9 points, and 17006-06 for 10 to 15 points.
