Popis:	This paper describes experimental procedures and techniques for measuring densities and/or refractive indexes of aqueous salt solutions between 25 and 200 [degrees]C and with 18.90-90.50 wt % mixed salt (LINO[sub 3], KNO[sub 3], and NaNO[sub 3]). An electrolyte solution of (LI, K, Na) NO[sub 3] slats in water was chosen for study because of its recent development as a potential high-temperature heat pump fluid, but any other appropriate fluid may be accommodated for study in the apparatus. The densities and refractive indexes are shown to represent a convenient way to measuring the concentration of salt (or water), and accuracies of [plus minus]0.8 and [plus minus]0.3 wt % total mixed salt were achieved by using the above two methods, respectively.
