Type K thermocouples (Nickel-Chromium/Nickel-Aluminum) are the most widely used temperature sensors due to their stability, fast response, and suitability for oxidizing environments. They provide reliable measurements from –328°F to +2192°F (–200°C to +1200°C), making them ideal for industrial ovens, kilns, plastics processing, scientific R&D, and general-purpose engineering applications.
Why choose Type K?
- Wide temperature range (–328°F to +2192°F)
- Fast response and high durability
- Low drift and excellent long-term stability
- Cost-effective for general-purpose applications

Type K Thermocouple FAQ
What are Type K thermocouples made from?
Type K uses Nickel-Chromium (positive) and Nickel-Aluminium (negative) conductors.
Why are Type K thermocouples so widely used?
They offer a wide temperature range, fast response, low drift and good durability in oxidising atmospheres.
What colour is Type K?
In ANSI colour codes, Type K cables use brown or yellow (if using extension grade cable) overall insulation with yellow (+) and red (–) cores.
