Product Details:
|
| High Light: | high temperature thermocouple wire,thermocouple lead wire |
||
|---|---|---|---|
TYPE E (CHROMEL vs Constantan) may be used in oxidizing, inert or dry reducing atmospheres, or for short periods of time under vacuum. Must be protected from sulfurous and marginally oxidizingatmospheres. Produces the highest EMF per degree o any standardized thermocouple.
