Digital refractometer DR301-95 – Precise measurements for laboratory, industry & on the go
The DR301-95 is both a high-quality mobile refractometer and a simple digital desktop device. In addition to the refractive index and sugar content, it can also measure the salt content (%) (NaCl or salinity). On request, the DR301-95 can be equipped with two further freely selectable scales (e.g. Oechsle, Baumé). Up to 5 measuring scales are possible in one refractometer.
It has a menu control that can be used to switch on automatic temperature compensation – against sucrose – for each scale. An alarm option can be set up for monitoring limit values in production processes.
The digital refractometer DR301-95 becomes a stationary laboratory refractometer with the supplied mains adaptor. For mobile use, it can be operated flexibly with a 9 V block battery. Typical areas of application are the food and beverage industry, pharmacies, laboratories, testing offices as well as research and teaching.
Thanks to the additional salt content scale (%), the device is also ideal for measuring salinity. In food production, it is used to analyze the sodium chloride content in brines, canned vegetables, soups and fruit juices.

Application Digital refractometers
The DR301-95 digital refractometer enables measurements with up to five different scales and requires only a minimum sample volume. Thanks to its wide measurement range of nD 1.3330-1.5318 and 0-95 % Brix, it is ideal for a wide variety of samples and applications.
Application example food industry
- Valid norms/standards: AOAC, OIML, ASTM, GLP, ICUMSA
- Application: Quality and purity control of raw materials and end products (including convenience products, canned vegetables, soups, fruit juices and brines) also ideal for measuring the salt content (%) on the production line.
- Rapid measurement of alcohol content and determination of sugar concentration (starch hydrolysis products, seasoning sauces)
- Advantage: Portable, handy, light, easy to clean
Application example hospitals and pharmacies
- Valid norms/standards: Pharmacopoeias (BP,JP, Ph. Eur.), GLP
- Application: Outgoing goods inspection or analysis of raw materials. Control of drugs according to Pharmacopoeia (infusion solutions, blood serums, pills, pastes, dialysis preparations) or analysis of body secretions
- Advantage: High reliability, the optional 5 scales can be read digitally.
- The automatic temperature compensation for sucrose can be switched on

Cleaning tips
The DR301-95 impresses with its versatility and is ideal for frequently changing samples in the laboratory, production and quality control.
The smooth stainless steel sample tray and the high-quality glass prism are designed in such a way that a wide variety of samples can be applied particularly easily. Residues can be removed quickly and completely – even with challenging or highly adhesive sample types.
We have compiled cleaning tips (expert advice) with which refractometers can be cleaned hygienically and are immediately ready for use again.
