Our Type R thermocouple wire is made from high-quality platinum-rhodium alloys—87% platinum and 13% rhodium for the positive leg, paired with pure platinum for the negative leg. This combo gives it excellent oxidation resistance and stability, making it ideal for high-temperature environments like industrial furnaces and aerospace testing. With a temperature range of 0°C to 1600°C (and short-term use up to 1700°C), it’s a versatile solution for demanding applications.

We offer Type R wire in various gauges, from 0.1mm to 0.5mm, and with insulation options like ceramic, alumina, or mineral-insulated sheaths to handle extreme heat and harsh conditions. Each batch is rigorously tested to meet standards like IEC 60584 and ASTM E230, ensuring consistent accuracy. Unlike some thermocouples, Type R provides reliable performance in oxidizing and inert atmospheres, though it needs protection in reducing environments. Whether you’re monitoring a glass furnace or a lab experiment, our Type R wire delivers the precision you need.

The thermocouple wire market is on a steady growth path, with demand surging in industries that rely on high-temperature precision. Recent data points to continued expansion through 2030, driven by advancements in steel production, aerospace, and glass manufacturing. Type R thermocouples are a favorite for applications requiring accuracy between 1000°C and 1600°C, thanks to their high rhodium content and stable performance. The rise of Industry 4.0 is also pushing for sensors that integrate with automated systems, providing real-time data for process optimization.

Sustainability is a big focus, with industries seeking durable, recyclable materials to cut costs and environmental impact. Platinum-based thermocouples like Type R are highly recyclable, making them a smart choice for eco-conscious operations. Innovations in insulation materials are also expanding the use of thermocouples in vacuum and inert environments. At DLX, we’re keeping up with these trends by offering customizable wires and investing in solutions that meet the demands of modern industry.

Applications

Our Type R thermocouple wire is a go-to for high-temperature applications. In steel production, it monitors furnaces and ladles, ensuring precise control during smelting and casting. Glass manufacturing uses it to track molten glass temperatures, critical for maintaining product quality. In aerospace, Type R wires measure turbine and exhaust gas temperatures, supporting safety and efficiency in jet engines. Research labs rely on it for experiments involving ceramics, alloys, and other high-temperature materials, where accuracy is non-negotiable.

The wire performs well in oxidizing and inert atmospheres, making it ideal for vacuum furnaces in semiconductor or aerospace applications. With proper insulation, it can handle mildly corrosive environments, though it’s not suited for reducing conditions without protection. Its high accuracy and long lifespan reduce downtime and maintenance costs, making it a cost-effective choice for industries that demand reliability.
