About this Table

Full Type E Thermocouple Table from −270 to 1000 °C in 1 °C steps. Values are the thermoelectric voltage in mV with the reference junction at 0 °C.

Basis: NIST ITS 90 reference functions as adopted in IEC 60584 1. Type E is Nickel Chromium vs Copper Nickel: the highest output of the standard types, good for small temperature changes.

How to use

Find the row for the tens of degrees, then move across to the units column: row 120, column +4 is 124 °C.
For negative rows the column is still added: row −20, column +4 is −16 °C.
To read temperature from a measured mV, add the mV for the terminal temperature first (cold junction compensation), then find the total in the table.

Notes

IEC colour code: violet positive wire with white negative. ANSI MC96.1: purple jacket.
Values are reference values; real sensors have a tolerance class (see the thermocouple tolerance table).

Frequently Asked Questions

What is the mV of a type E thermocouple at 100 °C?

6.319 mV with the reference junction at 0 °C.

What is the range of a type E thermocouple?

The reference function covers −270 to 1000 °C. The practical service range is narrower and depends on wire size and sheath.

Why do I need cold junction compensation?

The table assumes the reference junction is at 0 °C. At the terminals it is warmer, so add the mV for the terminal temperature before reading the table.
