✦ Synopsis

An assessment of four ddferent types of small low-cost platinum res=stance thermometers is reported They have relatwely large but reproducible residual resistances, and can be used =n place of the so-called standard platinum resistance thermometers for most purposes They are also very useful for thermometry =n a strong magnetic field In th=s respect, the thermometer with the largest residual res=stance performs best, and =s better than carbon glass res=stors above ~50 K A descnpt~on ~s also gwen of a s=mple cryostat that maintains constant temperature during magnet=c field sweep
