Thermocouple Calibration
Thermocouples are a type of temperature sensor used to convert thermal potential difference into electric potential difference. Thermocouples can measure wide temperature ranges and are used by many industries for various applications.
The main limitation of thermocouples is accuracy; temperature measurements with uncertainties less than 1 °C are difficult to achieve without expertise of a trained metrologist. Bagan thermocouple calibration service provides temperature measurement with an uncertainty of .14 °C for some thermocouples, and can help you select the best thermocouple for the application.

Calibration and Measurement Capability (CMC) is the smallest uncertainty of measurement that a laboratory can achieve within its scope of accreditation when performing more or less routine calibrations of nearly ideal measurement standards or nearly ideal measuring equipment.
Calibration
and Measurement Capabilities represent expanded uncertainties expressed at approximately the 95 %
level of confidence, usually using a coverage factor of k = 2. The actual measurement uncertainty of a
specific calibration performed by the laboratory may be greater than the CMC due to the behavior of
the customer’s device and to influences from the circumstances of the specific calibration.
Please note the actual measurement uncertainties achievable on a customer's site can normally be expected to be larger than the CMC found on the A2LA Scope. Allowance must be made for aspects such as the environment at the place of calibration and for other possible adverse effects such as those caused by transportation of the calibration equipment. The usual allowance for the actual uncertainty introduced by the item being calibrated, (e.g. resolution) must also be considered and this, on its own, could result in the actual measurement uncertainty achievable on a customer’s site being larger than the CMC.
