For your fresh delicacies


Measuring the sweetness of fruits and vegetables provides information about their quality. The sugar content can not only be used as an indicator for best timing in harvesting but also to determine the market value of fruits and vegetables or to decide whether they should better be used as a fresh or preserved product.

In combination with a mobile app, the SmartRef digital refractometer determines the sugar content in °Brix and additionally allows you to store and visualize the measurement results so that you can access the previous measurement data at any given time.
