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

- Robust housing and low device weight
- Operation Mains adaptor or battery
Digital on-site measurements at the touch of a button
The mobile measurement with a digital handheld refractometer saves time as random checks or the regulation of mixing ratios can be carried out directly on the site. The measurement results are determined at the touch of a button and shown on the display. Unlike in the case of the analogue handheld refractometers, the digital determination of reproducible measurement results does not depend on the user’s interpretation
Typical applications KRÜSS DR301-95
The digital hand-held refractometers DR301-95 are the ideal solution for the chemical, petrochemical, automotive, aviation, metal processing and food industry as well as for hospitals and pharmacies.
