Evaluation of the Ice-Water Mixture Thermocouple Reference Chamber.
Abstract
The evaluation of an ice-water mixture thermocouple reference chamber is described. The effect of preparation and of increasing the thermal load at various immersion depths on the initial temperature and life time are considered. It has been shown that accuracies of 0.01C can be achieved provided that the ice is made from distilled water, is 'shaved', thoroughly wetted and packed quite hard into the container. The re-entrant tube used to contain the thermocouples must be filled with a thermally conducting oil to just below the ice level and the depth of immersion must be sufficient for reasonable life times to be obtained.
