Application & Performance

Type K thermocouple alloy (Chromel vs Alumel) is engineered for use in oxidizing, inert, or dry reducing atmospheres. This reliable and accurate high-temperature material offers excellent performance in demanding industrial applications. Note: Limited exposure to vacuum environments and protection required from sulfurous and marginally oxidizing atmospheres.
