 Description: 
 Copper - Copper-nickel thermocouple (T-type thermocouple), also known as copper - constantan thermocouple, is also a low-temperature measurements of the best inexpensive metal thermocouple. It's positive (TP) is a copper, negative (TN) for the copper-nickel alloy, often of the constantan, nickel-chrome it - the constantan constantan EN common, and iron - the constantan constantan JN can not be universal, Although they call constantan, copper - copper-nickel thermocouple temperature measurement area for the cover of -200 ~ 350 ℃. 
 T-type thermocouple has good linearity, thermal electromotive force larger, high sensitivity, stability and uniformity better, cheaper, etc., especially in the temperature region -200 ~ 0 ℃ to use, better stability, year stability of less than ± 3μV, low temperature test can be used as second-class standard for low-temperature value transfer. 
 T-type thermocouple of copper cathode in the high temperature oxidation resistance is poor, it use the maximum temperature is limited.
