Compact laboratory refractometer for versatile applications
The ATR-BR is a stand-alone critical angle refractometer designed to measure liquid media from low to high viscosity, regardless of opacity and colour. It is adaptable to various production and laboratory applications thanks to a wide range of configurations, all while offering an excellent price-performance ratio.
Features of the critical angle refractometer
- Réfractomètre robuste
- Stand-alone device
- Stable, precise measurement
- Versatile applications
- Easy handling, user-friendly operation
- Excellent price-performance ratio
- Flat and small sample chamber for easy cleaning
Facile à utiliser
The newly designed casing provides more room for a larger LCD display and a splash-proof foil keyboard. Batch numbers can be entered directly, and simple forms can be created and printed with ease. A sample volume of just 0.3 mL is enough to achieve highly stable, precise measurements.
The user-friendly software of the critical angle refractometer allows practical features such as calculating the mean value, determining the standard deviation, and setting a measurement delay depending on the temperature.
Applications
- Chemical industry: solvents, organic polymers, distilled products, solutions of inorganic compounds
- Food industry: yoghurt, jam, fruit extract, syrup, honey, coffee extract, vegetable fat, albumen, chocolate, milk, baby food etc.
- Beverage: soft drinks, fruit juice, wine, beer
- Medical applications: serum, blood, urine
- Pharmaceutical/cosmetical industry: essences, essential oils, flavours
