Platinum
Platnium RTD's are an industry standard. They follow an industry standard curve from 73K to 873K with good sensitivity over the whole range. Platnium RTD's can also be used down to 14K. Because of their high reproducibility, they are used in many precision metrology applications. Platinum RTD's have limited packaging options, but they are inexpensive and require simple instrumentation. They are widely used in cryogenic applications at liquid nitrogen temperatures or greater.

Rhodium-Iron
Rhodium-Iron temperature sensors can be used over a wide temperature range, and are resistant to ionising radiation. Wirewound capsule versions (RF-800) have excellent stability and are widely used as secondary temperature standards by many national standards laboratories.

Thin-film Rhodium-Iron sensors have various packaging options, including the SD package and bare chip. They require similar instrumentation as a Platinum RTD, and are used in applications when packaging, size and temperature range prevent the use of Platinum or Cernox sensors.
