precision instrument for making measurements of the relative humidity (water activity): a hygrometer to drop at different temperatures

摘要

the present invention relates to a moisture meter accuracy in different tempu00e9ratures.une literature review is given on the different experimental methods for the determination of the relative humidities activities of aqueous solutions containing solvent and solute. the experimental approaches are particularly well suited to meet this objective can be divided into two categories.it measures the partial pressure of water vapour by means of static or dynamic and equilibrium quantities isopiu00e9stique measures for the study of non volatile electrolyte solutions.the purpose of this invention is a moisture meter accuracy at different temperatures ranging from 3 degrees to 200 degrees, based on the variation of the diameter of a droplet of salt solution and attached to a standard wire end above the solution, we will present a method was studied. ode to the measurement of the activity of water relative humidity of aqueous electrolyte solutions.this measure is based on the determination of equilibrium properties of liquid water. steam.
