Specifications
The ATR-P Refractometer by SCHMIDT + HAENSCH offers a wide range of measuring scales including Refractive Index (RI) and Sucrose (%Brix), with up to 1000 scales that can be freely defined. It has a measuring range of 1.32000 - 1.54000 RI and up to 95% Brix, with a resolution of 0.00001 RI and 0.01% Brix. The precision is ± 0.00002 RI and ± 0.02% Brix, and reproducibility is ± 0.00001 RI and ± 0.01% Brix. The device operates within an ambient temperature range of +10° to +40°C and features automatic temperature compensation from +5° to +50°C.

Temperature Measurement and Control
The refractometer uses an NTC sensor for sample temperature measurement, placed inside the prism. Temperature control is achieved through an external water bath, with a range of 5°C to 50°C.

Measurement Modes
It supports single sample or flow-through measurement and can be used horizontally or vertically. The prism is made of sapphire, and the light source is an LED with a wavelength of 589 nm.

Display and Operation
The device features a 7" touchscreen display with 800 x 480 pixels and 16-bit colors. It can be operated via touchscreen, keyboard, mouse, barcode reader, or remotely via PC.

Interfaces and Conformity
The refractometer includes multiple interfaces: 1 x RS232 C serial, 3 x USB (A), 1 x USB (B), and 1 x Ethernet. It conforms to various standards including International Pharmacopoeia, ASTM, AOAC, DIN, FDA, and ICUMSA.

Highlights
The device is robust with a stainless steel measuring head suitable for rough environments, offering high performance and accuracy with continuous measurement capabilities. It features easy calibration, GLP/GMP compliance, and full traceability of records with external LIMS integration. The VariControl system provides maintenance-friendly remote diagnostics and intuitive user handling.

Applications
The ATR-P Refractometer is versatile, used for determining refractive index, dry substance, mass percent, and Brix measurement with automatic temperature compensation. It is applicable in qualitative and quantitative analysis of dissolved solids, sugars, and other substances. Typical applications include the sugar industry, beverages, and food products like oils from palm, corn, sunflower, and soya.

Weight and Dimensions
The measuring head weighs 4.5 kg with dimensions of 200 x 160 x 135 mm, while the VariControl weighs 2.0 kg with dimensions of 250 x 170 x 180 mm.
