Handheld refractometers

Digital Handheld Refractometers

Perform Precise Measurements Easily and On the Go

Digital handheld refractometers combine the flexibility of classic handheld models with the high accuracy of digital measurement technology. They enable fast and precise determination of refractive index or specific scales such as °Brix directly on site without relying on laboratory instruments. Thanks to their digital display, reading errors are eliminated, ensuring reliable results.

They are used in the food and beverage industry, viticulture, agriculture, pharmaceuticals, and chemicals. Compact, lightweight, and easy to clean, many models also offer automatic temperature compensation for precise measurements even under changing ambient temperatures.

Your benefits at a glance:

  • Fast and precise results, mobile and flexible

  • Digital display for easy, error-free reading

  • Compact design for on-site use

  • Automatic temperature compensation in many models

Discover our selection of digital handheld refractometers and perform your measurements easily, reliably, and accurately – wherever you need them.

KRÜSS Digital handheld refractometer KRÜSS DR301-95

The KRÜSS DR301-95 is both a high-quality mobile handheld device and a simple digital desktop device. In addition to the refractive index and sugar content, it can also measure the salt content (%) (NaCl). On request, the DR301-95 can be manufactured with any two other scales. Via the menu control it is possible to switch on the automatic temperature compensation for each scale – with measurement reference to sucrose. An alarm option can be set up for monitoring limit values in production processes. The supplied Mains adaptor turns the DR301-95 into a small laboratory refractometer. In mobile use, it is operated with a 9 V block battery. The DR301-95 is used in the food and beverage industry, in pharmacies, laboratories
