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

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. More information

Temperature control range: +5 to +100 °C
Measuring range: 1,29000 to 1,7000 RI (100 %Brix)
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).

Inline Process Refractometers (iPR) from SCHMIDT+HAENSCH are used in a wide range of process monitoring applications and are available as stand-alone solutions with integrated display or connected to a PLC. The iPR measuring heads can be combined with various process sensors such as O2, CO2, pH, turbidity or conductivity to an intelligent sensing station, complying with regulations in food, beverage and pharmaceutical industries. To avoid the contact of highly concentrated acids or corrosive substances with stainless steel surface, special PTFE inline housings are available. More information
