Product Details:

Digital refractometer is an optical instrument that employs the measurement of refractive index to determine the concentration in aqueous solutions. The method is both simple and quick. Samples are measured after a simple user calibration with deionized or distilled water. Within seconds the instrument measures the refractive index of the sample and converts it to % concentration units. This instrument eliminates the uncertainty associated with mechanical refractometers and is easily portable for measurements in the field. The measurement technique and temperature compensation employ methodology recommended in the internationally standard. Temperature ( in °C or °F ) is displayed simultaneously with the measurement on the large dual level display along with icons for Low Power and other helpful message codes.
