Refractometers

Schmidt + Haensch GmbH & Co

Visual hand-held refractometers are classic, visual refractometers used for the determination of the refractive index of liquid media of low or high viscosity. They are mainly used for quick on-the-spot-control of process streams and the field analysis in fruit and vegetable plantations.

Applications / Determination of:
• % Brix (4 different measuring ranges available)
• % Oechsle
• Urine (0 – 12 g/dl)
• Salinity tests (0 – 28 %)
• Wine measurements (0 – 32 %Bx; 0 – 140°Oe)

Different models of hand-held refractometers for special applications and with different resolution and precision are available. More information

The DHR-95 digital hand-held refractometer (Brixmeter) with 5-digit, full view LCD screen displays results in 2 seconds. The device is designed for the measurement of liquid media from low to high viscosity.

The DHR-95 offers a reliable automatic temperature compensation within +5 to 70 °C for 0 - 80 Brix and further convinces with a handy design and simple operation.

Various models are available, for applications including honey, wine, saline, glycol or DEF. For more information, please check the technical specifications or contact us. More information

Measuring range of the scale (refractive index):
1.3000 - 1.7200 RI or 0 - 95% Brix
Precision: +/- 0.0002 RI / 0.1 % Brix

The visual ABBE-refractometer AR12 is designed for the determination of concentration and purity control of liquid media with high or low viscosity and solids. This refractometer is equipped with hose connections at the prism unit for the thermostatisation of the optical parts. The temperature is measured with a digital thermometer. The measuring principle is based on the law of Snellius (law of refractive index) and is able to measure with transmitted or totally reflected light. With a contact fluid, even solids can be measured. Optionally, an illumination unit is available for prism and scale illumination with a LED. The visual ABBE-refractometer AR12 is mostly used in the fast control of liquids and the “in-field analysis“. More information

Highest measuring accuracy
Wide range of different models for versatile applications (incl. fully automatic spectral refractometers)

High-performance refractometers for the determination of mixing ratios and quality-quantity control of solutions. Suitable also for solids and aggressive solutions. Single-sample or flow-through measurement modes are available.

Typical applications are the determination of refractive index, dry substance, mass percent as well as Brix measurements and standard scales (Brix, Oechsle, Zeiss, Fat, Honey).
Conformity: International Pharmacopoea, ASTM, AOAC, DIN, FDA, ICUMSA and others.

There are various models available, depending on the measuring range, accuracy, resolution and application: VariRef (A, B, C), ATR-BR (basic refractometer) and ATR-L (multi-wavelength refractometer). More information
