Understanding Thermocouple Types: Type K vs. Type J

Thermocouples are distinguished by their material composition, which determines their temperature range, sensitivity, and cost.

• Type K (Chromel-Alumel):

  • The Most Common Choice: Type K is the most widely used general-purpose thermocouple due to its wide temperature range and affordability.
  • Wide Temperature Range: It can measure a broad spectrum of temperatures, typically from -200°C to +1250°C (-330°F to +2282°F), although this specific probe is rated for -50°C to 600°C.
  • Sensitivity: It has a sensitivity of approximately 41 µV/°C.
  • Color Code: The standard wire color code for Type K is a yellow positive (+) lead and a red negative (-) lead.

• Type J (Iron-Constantan):

  • More Restricted Range: Type J has a narrower temperature range, commonly from about -40°C to +750°C (-40°F to +1382°F). It is often used in lower-temperature applications where its higher sensitivity is an advantage.
  • Higher Sensitivity: It offers a slightly higher sensitivity of around 50 µV/°C, allowing for more precise readings within its range.
  • Color Code: The standard wire color code for Type J is a white positive (+) lead and a red negative (-) lead.

In summary, while Type J offers higher sensitivity for specific applications, the Type K probe provides greater versatility with its exceptionally wide measurement range, making it the preferred choice for general-purpose ambient air and gas temperature monitoring.
