Chromel / Alumel Thermocouple Bare Wire (Type K)

Description:

NiCr-NiSi (Type K) thermocouple finds the widest use in all basemetal thermocouple, at temperature above 500 °C.The main chemical composition of positive leg NiCr (KP) are Ni≈90% and Cr≈10%; negative leg NiSi (KN) are Ni≈97% and Cr≈3%. The operating temperature range is -200~1300°C(for short term) and 0~1100°C( for long term) .

Type K thermocouple has strong resistance to oxidation than other base metal thermocouples. It has high EMF against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in the following case:

(1) Alternatively oxidizing and reducing atmosphere,

(2) Atmosphere with sulphur gases,

(3) Long time in vacuum,

Type K Temperature Range:

(1)Thermocouple grade wire, -200~1300℃(for short term) and 0~1100℃( for long term)

(2)Extension wire, 32 to 392F (0 to 200C)

Working temperature:

Diameter/mm	Long time Working	Short period Working
Diameter/mm	temperature/°C	temperature/°C
0.3	700	800
0.5	800	900
0.8,1.0	900	1000
1.2,1.6	1000	1100
2.0,2.5	1100	1200
