Thermocouple wire
Type K (Chromel / Alumel)
Type K is the ‘general purpose’ thermocouple. It is low cost and, owing to its popularity, it is available in a wide varietyof probes.
Thermocouples are available in the -200 °C to +1200 °C range. Sensitivity is approx 41 µV/°C. Use type K unless you have a
good reason not to.
Type E (Chromel / Constantan)
Type E has a high output (68 µV/°C) which makes it well suited to low temperature (cryogenic) use. Another property is that
it is non–magnetic.
Type J (Iron / Constantan)
Limited range (-40 to +750 °C) makes type J less popular than type K. The main application is with old equipment that can not
accept ‘modern’ thermocouples. J types should not be used above 760 °C as an abrupt magnetic transformation will cause
permanent decalibration.
Type N (Nicrosil / Nisil)
High stability and resistance to high temperature oxidation makes type N suitable for high temperature measurements without
the cost of platinum (B,R,S) types. Designed to be an ‘improved’ type K, it is becoming more popular.
Thermocouple wire, platinum wire
Thermocouple types B, R and S are all 'noble' metal thermocouples and exhibit similar characteristics. They are the most stable
of all thermocouples, but due to their low sensitivity (approx 10 µV/°C) they are usually only used for high temperature
measurement (>300 °C).
Type B (Platinum / Rhodium)
Suited for high temperature measurements up to 1800 °C. Unusually type B thermocouples (due to the shape of theirtemperature
/ voltage curve) give the same output at 0 °C and 42 °C. This makes them useless below 50 °C.
Type R (Platinum / Rhodium)
Suited for high temperature measurements up to 1600 °C. Low sensitivity (10 µV/°C) and high cost makes them unsuitable for
general purpose use.
Type S (Platinum / Rhodium)
Suited for high temperature measurements up to 1600 °C. Low sensitivity (10 µV/°C) and high cost makes them unsuitable for general purpose use. Due to its high stability type S is used as the standard of
calibration for the melting point of gold (1064.43°C).
