  We describe the design and performance of a series of fast, precise current
sensing noise thermometers. The thermometers have been fabricated with a range
of resistances from 1.290 $\Omega$ down to 0.2 m$\mathrm{\Omega}$. This results
in either a thermometer that has been optimised for speed, taking advantage of
the improvements in superconducting quantum interference device (SQUID) noise
and bandwidth, or a thermometer optimised for ultra-low temperature
measurement, minimising the system noise temperature. By using a single
temperature calibration point, we show that noise thermometers can be used for
accurate measurements over a wide range of temperatures below 4 K. Comparisons
with a melting curve thermometer, a calibrated germanium thermometer and a
pulsed platinum nuclear magnetic resonance thermometer are presented. For the
1.290 $\mathrm{\Omega}$ resistance we measure a 1 % precision in just 100 ms,
and have shown this to be independent of temperature.
