Thermometer Calibration Services
Thermometer Calibration You Can Rely On
QCS’s state-of-the-art Thermometry Laboratory is accredited by the American Association for Laboratory Accreditation (A2LA) under Certificate 1550.01. We provide expert calibration for liquid, digital, infrared (IR), and contact thermometers using direct comparison methods aligned with the International Temperature Scale of 1990 (ITS-90).
Our capabilities include:
-
Liquid baths (Ertco, Hart, Fluke): -80°C to 150°C
-
Fluke drywell: 151°C to 400°C
-
High-temp furnace: up to 1000°C
NIST Traceable, ISO-Compliant Results
Every calibration is performed using test methods such as NIST SP 250-23 and ASTM E77, ensuring results are traceable to the SI through NIST. Our certificates meet the stringent requirements of ISO/IEC 17025:2017 and ANSI/NCSL Z540-1-1994, providing confidence in compliance and measurement accuracy.
Testing
Thermometers are typically tested at 3 points using ASTM E1 recommended test points or to customer requested test points if requested. Tolerances are from ASTM E77, NIST SP 230-23, or manufacturer’s provided tolerances.
Uncertainties
Measurement uncertainties are calculated using methods consistent with the Guide to the Expression of Uncertainty in Measurement (GUM) with a k factor of 2 for an approximate 95% level of confidence.
