Handheld (Digital)

Digital handheld refractometers are generally more precise than traditional handheld refractometers, but less precise than most benchtop refractometers. Instruments are available with multiple scales, or the ability to input a special scale using known conversion information.

These instruments operate on the same general critical angle principle as a traditional handheld refractometer and are IP65 (IP Code) water-resistant, and thus washable under a running tap. The difference is that light from an LED light source is focused on the underside or a prism element.

This means that the instruments may be used where natural daylight is poor or absent. Atago have developed the renowned PAL series and the slightly more refined Pallette series instruments which have the widest range of calibation options of any manufacturer, offering units of measure for your application.
