Product Overview

TANKII 0.2 * 5 mm Tailor-Made Flat Wire K Type Thermocouple Ribbon Wire for Sensor Accessories

K Type Thermocouple Wire is a widely used temperature-sensing alloy wire engineered for accurate and reliable temperature measurement in industrial applications. It consists of two dissimilar alloy conductors: Nickel-Chromium (NiCr / Chromel) as the positive leg (+) and Nickel-Aluminum (NiAl / Alumel) as the negative leg (−).

K Type Thermocouple Wire offers excellent oxidation resistance, good thermal stability, and dependable thermoelectric performance across a wide temperature range. As a professional manufacturer and supplier of thermocouple alloy wires, we provide high-quality K Type Thermocouple Wire in various diameters, surface conditions, and accuracy classes to meet diverse industrial requirements.

Tankii's Thermocouple Types

What differentiates one thermocouple from another is the metals in its two wires: the positive leg and the negative leg. Because each thermocouple type uses a different pairing, they differ in temperature limits, process conditions (inert, oxidizing, reducing atmospheres, heavy vibration), and so on.
