Precise results – regardless of user qualification
The DR201-95 digital handheld refractometer delivers extremely reliable measurement results – almost regardless of the user’s expertise. It is a compact and mobile handheld refractometer and can be found in many industries. The device offers an exceptionally wide measurement range that enables the most precise analyses in a wide variety of applications. Its high-quality technical equipment is so impressive that it can even be seen as an exhibit in the„Chemistry“ exhibition at the Deutsches Museum in Munich.
The device measures both the refractive index (nD) and the sugar content in %Brix of liquid and viscous samples. The automatic temperature compensation for the BRIX scale ensures that reproducible and stable results are achieved even under changing ambient conditions – ideal for sugary drinks, confectionery and many other applications. The device is splash-proof and meets the IP64 standard.
The digital handheld refractometer is used for analysis in the food and beverage industry on the production line, in pharmacies, food production, automotive or mechanical engineering and also in pharmaceuticals.

Application Digital refractometers
The DR201-95 digital refractometer provides reliable, reproducible measurements. Thanks to its digital measured value acquisition with automatic temperature compensation, subjective user interpretations are no longer necessary – the result can be validated and is reliable at all times.
With its exceptionally wide measurement range of nD 1.3330-1.5318 and 0-95 % Brix, the device covers an enormous range of measurements for samples and applications. At the same time, the digital handheld refractometer only requires a minimum sample volume, which makes the measurement process particularly efficient.
In short: Many customers rely on the DR201-95, it is one of the KRÜSS Optronic bestsellers: It combines high precision, easy operation and maximum flexibility for a wide variety of samples and applications.
Application example chemical industry
