Choosing between Type K & Type J CHT Thermocouple Sensors
The primary differences between the two thermocouples are:
Measuring Range:
Type K = -330°F to +2460°F (-200°C to +1250°C)
Type J = -40°F to +1382°F (-40°C to +750°C)
Sensitivity:
Type K = approximately 41 µV/°C
Type J = approximately 55 µV/°C
If you already own a gauge it is important that you use the correct thermocouple sensor type, otherwise the result will be incorrect CHT temperature readings due to mismatched sensitivities.
Thermocouple can be identified by wire color. Use the figures below to identify Type K & J Thermocouples:
