Refractometers of series A is an advanced and fully professional, automatic laboratory refractometers equipped with a high-resolution CCD detector. Provide accurate and precise measurements and high repeatability of the results read. Perform automatic measurement in units of refractive index (nD) or by measuring the concentrations of the sugar % Brix scale. Devices enable obtaining fast, accurate and precise results. Using automated laboratory refractometers increases the efficiency of research and also eliminates human error.
