Thermal Calibration is a comparison between standard and the measure thermal parameters of instruments. It not only includes comparison of parameters but also set span or offset adjustments & take into permissible range if facilities are available. Typically, the accuracy of the standard should be minimum three times the accuracy of the measuring device being tested (As per NABL norms) & we maintain more than this ratio by our accurate calibrator which calibrated by NABL Lab. In this calibration either externally thermal sources or electrical signals like mV, mA, V, Ω are given.
