Easy to Use

The sample is placed on a level surface and measurement results are returned within seconds. For example, with a hand refractometer it is quite simple to determine the point of harvest by measuring the sugar content in apples. A volume of 0.1 ml fruit juice is already sufficient for evaluation.

The Brix scale is temperature compensated within +5 to 70 °C. Further scales are available upon request.


Handheld refractometers are most used in agriculture for point of harvest determination, as well as in the food and beverage industry.

DHR models are available with two refractometer scales that can be used to analyze such materials as honey, wine, saline, glycol, and antifreezer.
