The following table lists typical thermocouples.
Of them, Anritsu Meter employs two types E and K as standard ones because they deteriorate less than the types J and T in an oxidizing atmosphere and are marketable at lower prices than the types R, B and S.
With a wider measurable temperature range, they are applicable to a variety of uses.
| Type | Alloy combination |
| E | Chromel-Constantan |
| K | Chromel-Alumel |
| J | Iron-Constantan |
