Type J Immersion and General Purpose Thermometer Probe

The primary difference between Type J and Type K thermocouples is the measuring range, and the sensitivity. Type K is the most common general-purpose thermocouple with a sensitivity of approximately 41 μV/ degrees C. A wide variety of probes are available in its −50 degrees C to +900 degrees C / -58 degrees F to +1652 degrees F range. Type K wire color standard is yellow + and red -. Type J has a more restricted range of −50 to +400 degrees C, but higher sensitivity of about 50 μV/ degrees C. Type J wire color standard is white + and red -.
