Type K Thermocouple Wire
Request a Quote
Type K thermocouple alloy wire (Chromel vs. Alumel) is designed for use in oxidizing, inert, or dry reducing atmospheres. It can withstand short-term exposure to vacuum conditions, ensuring stable and precise temperature measurements. However, it should be protected from sulfur-containing environments and mildly oxidizing conditions, as these can affect its performance. Type K thermocouples offer high reliability and accuracy at elevated temperatures, making them a preferred choice for various industrial applications.
