Type K Reference Chart °F; Type K Reference Chart °C; This is the most common thermocouple type that provides the widest operating temperature range. The most common types (calibrations) are J, K, T, and E. Although the thermocouple calibration dictates the temperature range, the maximum range is also limited by the diameter of the thermocouple wire. Generally, the voltage is in the microvolt range and care must be taken to obtain a usable measurement. The type K is commonly found in nuclear applications because of its relative radiation hardness. Although thermocouple calibration dictates the temperature range, the maximum range is also limited by the the diameter of the thermocouple wire. Accuracy: The accuracy for R-type is Typical: +/- 1.5C (or) +/- .25% particular error limits: +/- 0.6C or 0.1%.
