Compact Refractometer by S+H

Compact Refractometer

The SCHMIDT + HAENSCH ATR-BR is a stand-alone, critical angle refractometer for measuring liquid media from low to high viscosity, independent of opacity and color. It is adaptable to different applications in production and laboratory thanks to a broad variety of configurations while having an excellent price-performance ratio.

ID-N° 11890

Checkpoints

  • Robust refractometer
  • Stand-alone device
  • Stable , precise measurements
  • Versatile applications
  • Easy handling, user-friendly operation
  • Excellent price-performance ratio
  • Flat and small sample chamber for easy cleaning

Easy in Use

A sample volume of 0.3 ml is sufficient for a very stable measurement of high quality and precision. The software of the ATR-BR, designed close to the practice makes it possible to calculate the mean value and to determine standard deviation and adjustable measuring delay for special measurement in dependence of the temperature.

Applications

In the chemical industry, ATR-BR can be used for analyzing a range of compounds, such as solvents, organic polymers, distilled products, or solutions of inorganic compounds. In the food and beverage industry, the ATR-BR can be applied to analyze yoghurt, jam, fruit extract, syrup, honey, coffee extract, vegetable fat, albumen, chocolate, milk, and baby foods. The quality of soft drinks, fruit juice, wine, and beer can be controlled. Medical applications include analysis of serums, blood, and urine. In the petrochemical industry, ATR-BR can be used to monitor e.g. oils, fats, waxes, naphthalenes, raw oils, varnishes, paints.

Product in depth

Up to ten user-defined scales, one of which is programmed as Brix scale by the factory, can be programmed. The casing design offers more space for a bigger LCD display and a splash proofed foil keyboard enabling to batch numbers to be entered directly. The user friendliness and easy handling of the ATR-BR also allows for the creation and printing of forms. All functions may also be controlled via PC using the remote control program. The ATR-BR also has a serial to Ethernet (local area network) converter for data transfer.
