A high resolution thermometer was developed using a dilute alloy of Mn in Pd as the magnetic sensing element instead of the traditional paramagnetic salt. Use of the alloy material facilitated a significant decrease in the total mass of the device to about 3.5 g. The noise and drift of the device were measured and found to be comparable with that of the larger HRTs used on past flight experiments. The origin of the noise observed in state-of-the-art HRTs and the potential of the new thermometric material for achieving lower noise figures is discussed.
