HANNA, HI 96821 Sodium Chloride Refractometer For The Food Industry

HANNA offers the HI 96821 digital sodium chloride refractometer to meet the requirements of the food industry. This optical instrument that employs the measurement of the refractive index to determine sodium chloride concentration in aqueous solutions used in food preparation. It is not intended for sea water salinity measurements. The measurement of refractive index is simple and quick and provides the user an accepted method for NaCl analysis. Samples are measured after a simple user calibration with deionized or distilled water. Within seconds the instrument measures the refractive index of the solution. The digital refractometer eliminates the uncertainty associated with mechanical refractometers and is easily portable for measurements where you need them. The instrument utilizes internationally recognized references for unit conversion and temperature compensation. It can display the measurement of NaCl concentration 4 different ways: g/ 100 g, g/ 100 mL, Specific Gravity, and ° Baumé . Temperature ( in ° C or ° F) is displayed simultaneously with the measurement ( on 3 of the ranges) on the large dual level display along with icons for Low Power and other helpful message codes. Order Information: Supplied with battery and instruction manual.
