We provide calibration services for liquid-in-glass, digital, bi-metal, thermocouple, thermistor, and RTD thermometers. Temperature instruments are calibrated by the comparison method with instruments traceable to the National Institute of Standards and Technology (NIST). We follow the ITS-90 reference guide. Specifications and tolerances are those published by the manufacturer unless specified otherwise. Standard calibration includes three measurement points and includes comprehensive calibration documentation and a calibration label affixed to the instrument. Additional measurement points are available for an additional charge per point.
