Type E thermocouple table (°C)
Thermoelectric voltage in millivolts of a type E thermocouple with the reference junction at 0 °C, from the NIST ITS-90 reference functions (IEC 60584-1), from -270 °C to 1000 °C.
Values in mV
Each row is a 10-degree step; the column adds the units digit (subtracts it in rows below zero). Example: 100 + 5 → 105 °C.
