LNX LPX Chromel Copel High Temperture High precision Type L Thermocouple Extension Bare Wire Class 1
TYPE L (CHROMEL vs Copel) 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 oxidizing atmospheres. Produces the highest EMF per degree o any standardized thermocouple.
