Refractometers

The Kruess Optronics range of optical instruments combines the highest quality German optics with an advanced optical design and precision mechanical parts. Kruess automatic digital instruments with processor control are available together with conventional analog optical instruments and Kruess hand held devices. Kruess offers a calibration & maintenance service for its range of laboratory instruments.

 

Kruess Automatic Digital Refractometer DR6000 series of digital refractometers deliver highly accurate and reproducible measurement results, offer semi-automatic and fully automatic working, and are easily integrated into existing laboratory workflows. There are three different model groups available for the different requirements of temperature control and automation options.

 

 

 

Kruess Process RefractometersThe inline process refractometers PR21S and PR21S-T are installed in pipelines of production facilities in order to control and regulate the concentration, mixing and fermentation processes. Thanks to the standardised connections, the measurement devices can be easily installed in pipelines. The measuring chamber is made of stainless steel, the measurement prism consists of scratch-resistant and especially chemical-resistant sapphire and is designed to prevent solids from sticking.

The Atline process refractometer PRB21S are installed in tanks or boilers using tube connections for the continuous monitoring and control of the concentration of liquids. The sample flows via the bypass into the measurement chamber made of stainless steel. The measurement prism consists of scratch-resistant sapphire and is resistant against solvents and acids.

 

ABBE Refractometers The AR4 determines the refractive index between nD 1.3000–1.7200 and the sugar content in the range of 0–95 %Brix of liquid, viscous as well as solid samples. Dry substance content in % and the dispersion value nF-nC can be calculated.
The AR2008 determines the refractive index between nD 1.3000–1.7200 and the sugar content in the range of 0–95 %Brix of liquid, viscous as well as solid samples. The dry substance content in % and the dispersion value nF-nC can be calculated. The output of the measurement results is performed digitally. The refractive index of the Brix value is shown on the LED display together with the temperature.

Digital Hand Refractometers 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
Hand Refractometers Handheld refractometers are barely bigger than a torch and can be used anywhere in mobile applications. They are especially easy to use, very robust and require no batteries. The devices differ mainly in the selectable scales, e.g. for the determination of the salt content, water content in honey, serum protein content, Oechsle, Brix and potential alcohol content as well as ethylene- and propylene glycol content. No manual conversion is required thanks to the scales and application errors are ruled out.
