 K 
 Chrome-nickel 
 Ni-Al 
 -200 ℃ ~ 1250 ℃ 
 For clean oxidation or can not afford the chemical action of the environment is not suitable for a vacuum environment or smelting applications (hypoxia), there are large temperature measuring range 

 J 
 Iron 
 Nickel and copper 
 0 ℃ ~ 750 ℃ 
 Suitable for lack of oxygen, vacuum, can not afford the chemical action of the environment, does not apply to high-temperature oxidation environment is not recommended for low temperature 

 T 
 Copper 
 Nickel and copper 
 -200 ℃ ~ 350 ℃ 
 Suitable for moderate oxidation, smelting, vacuum and can not afford the chemical action of the environment can also be used in a damp environment, applies to room temperature and low temperature the amount of measured 

 E 
 Chrome-nickel 
 Nickel and copper 
 -200 ℃ ~ 900 ℃ 
 Suitable for oxidation or can not afford the chemical action of the environment, not suitable for a vacuum environment or smelting applications (hypoxia), temperature change, the higher the EMF change 

 S 
 Platinum / rhodium 10% 
 Platinum 
 0 ℃ ~ 1450 ℃ 
 Suitable for oxidation or can not afford the chemical action of the environment can not be inserted into the metal tube, careful not to be contaminated, suitable for the measured high temperature 

 R 
 Platinum / rhodium 13% 
 Platinum 
 0 ℃ ~ 1450 ℃ 
 Suitable for oxidation or can not afford the chemical action of the environment can not be inserted into the metal tube, careful not to be contaminated, suitable for the measured high temperature 

 B 
 Platinum / 30% rhodium 
 Platinum / 6% rhodium

 Suitable for oxidation or can not afford the chemical action of the environment, can not be inserted in the metal tube, careful not to be contaminated suitable for the high temperature of measurement, usually used in the glass industry 

 N 
 Nickel chromium / 14.2% / 1.4% silicon 
 / 4.4% Ni / Si / 0.1% magnesium 
 -270 ° C ~ 1300 ° C 
 Can replace the K-type is more stable at high temperature measurement 


 (b) platinum temperature resistance body 

 Use of platinum inherent impedance increased with increasing temperature characteristics of platinum wire wound on mica or ceramic pipes made 

 Because the highest purity platinum in the metal, the higher the purity, the resistance versus temperature characteristics of the more consistent, and the higher the temperature coefficient of resistance, temperature range up to -200 ~ 850 ℃. 

 Pt100/JPt100 0 ° C impedance of 100 ohm 

 JPt100 old specification (JIS C1604 ~ 1981) the temperature coefficient of 3916ppm / ° C 

 The Pt100 new specifications (JIS C1604 ~ 1989), temperature coefficient of 3850ppm / ° C
