Copper resistance (WZC) |
Cu50 |
-50~150 |
50±0.05 |
1.428±0.002 |
Good stability and affordability; But with a large volume and low mechanical strength |
|
Cu100 |

Nickel resistance (WZN) |
Ni100 |
-60~180 |
100±0.1 |
1.617±0.003 |
High sensitivity and small size; But the stability and reproducibility are poor |
|
Ni300 |
300±0.3 |
1.617±0.003 |
||||
Ni500 |
500±0.5 |
1.617±0.003 |
||||
Low temperature thermistor |
Indium resistance |
3.4~90K |
100 |
Good reproducibility, with sensitivity ten times higher than platinum resistors in the temperature range of 4.5-15K; But the reproducibility is poor, the material is soft, and it is prone to deformation |
||
Rhodium iron thermistor |
2~300K |
20. 50 or 100 R4.2k/R273kApproximately 0.07 |
Has high sensitivity, good reproducibility, and can perform precise measurements within the temperature range of 0.5-20K; But the long-term stability and reproducibility are poor |
|||
Platinum cobalt thermistor |
2~100K |
100 R4.2k/R273kApproximately 0.07 |
Good thermal response, small natural size, good mechanical properties, and significantly higher sensitivity than platinum when the temperature is below 300K; But it cannot be used as a standard thermometer |
