Experience rapid and precise temperature sensing with our high-quality bare wire Type K thermocouples. As the most popular general-purpose industrial thermocouples, these sensors offer an unbeatable balance of durability, a wide temperature range, and cost-effectiveness. Ideal for applications where speed and direct contact are crucial, our bare wire design ensures minimal thermal mass for an exceptionally fast response time to temperature changes.
Key Features & Benefits

Ultra-Fast Response Time: The exposed, bare wire junction provides direct thermal contact, allowing for immediate reaction to temperature shifts in dynamic environments.
Wide Temperature Range: Effectively measure across a vast span, typically from -200°C to +1260°C (-328°F to +2300°F), with bare wire applications capable of handling up to 1370°C for short durations.
Durable & Reliable: Constructed from high-quality Chromel (Nickel-Chromium) and Alumel (Nickel-Aluminum) alloys, these sensors offer good resistance to oxidation in clean, dry atmospheres, ensuring long-term performance.
High Sensitivity: With a sensitivity of approximately 41 µV/°C, our Type K thermocouples provide accurate, consistent data for precise process control.
Cost-Effective Solution: Benefit from a high-performance temperature measurement solution that is more affordable than noble metal alternatives like Type R or S thermocouples.
