Type NAR-1T-Liquid: The Abbe Rerfactometer for liquid sample measurement only. It has the Refractive Index Scale and the Brix scale, and it comes with D-line (589nm) light source. Calibration can be achieved using distilled water.

Type NAR-1T Solid: Abbe Refractometer for solid sample measurement (it can also be used to measure liquid samples). It has the Refractive Index Scale and the BRIX scale, and it comes with D-line (589nm) light source.

Type NAR-2T: Designed for use with substances requiring measurement at high temperature.

Type NAR-3T: Developed to give improved measuring accuracy and ease of use. This has been achieved by making fundamental improvements to the optical system, utilizing a larger scale, incorporating a high intensity lamp and using a double control knob to give quick and finer control. With digital thermometer.

-Digital output of the measurement results

• With serial interface
• An automatic temperature compensation for the Brix scale can be optionally connected
• Optional: Measurement of the refractive index within the temperature range of 5 to 80 °C in combination with circulation thermostat PT80

The PT31 circulation thermostat is equipped with high performance functions. The device is ideally suited for applications requiring a temperature range at a constant level. The robust locking mechanism of the PT31 provides a sturdy connection and ensures constant temperature control of the medium.

• Temperature control using Peltier technology
• Space-saving, sturdy design
• Suitable for operation with non-flammable liquids (water or water/glycol mixture)

Very simple operation, where only the refraction boundary line has to be moved to the measurement cross hairs. The refractometer displays measurements directly (as a refractive index or in Brix (%)) in digits together with temperature. Measurements can be taken easily by anyone using this refractometer without taking an analogue scale reading in advance. Dispersive value can not be measured using this refractometer.

The laboratory refractometers Abbemat are equipped with the most important refractometric concentration beams, whereby further methods can be installed. They are characterised by fast measurements with high accuracy and are maintenance-free. For Abbemat 3200 and 3100 the built-in temperature control unit regulates the temperature, while the Abbemat 3000 provides automatic temperature correction.

• Compact device according to DIN A 4 size
• Sample trough with smooth, easy to clean surface and optimal shape of the measuring area
• 5.8" touchscreen for clear presentation of the measurement results
• More than 200 additional scales available on request
• 3 years warranty

The DR6000 refractometers work with hardly any service and are very quiet, good for long-term work in the lab. Very easy to operate due to an intuitive touch screen. Optional connections to printer, PC or network provide highest flexibility. High precision through integrated peltier thermostat (T-model). Flow measurement cells enable continuous measuring (TF-model). The devices are used wherever a substance in watery solutions has to be measured.
Areas of usage: beverage, chemistry, pharma, food, paper, sewerage, textile, petrochemistry, cosmetics.

The RX-5000, RX-5000 Alpha and RX-5000Alpha Plus are reliable and cost effective instruments with a measurement accuracy of ±0.03% Brix and ±0,00004nD. An excellent alternative to traditional Abbe refractometers and essential to any QC / QA lab. Equipped with 60 programmable user scales and 4 level password protection feature.
RX-5000 is designed to connect to an external circulating waterbath. RX-5000 Alpha and RX-5000Alpha Plus are equipped with a Peltier thermo module. RX-5000Alpha Plus has the highest accuracy of the RX series. All refractometers can be connected with an optional printer.

The most accurate refractometer in the world is now even more stylish, smart, and functional. Featuring intuitive touch screen technology, the new RX-i series makes navigation and selection a breeze. The RX-5000i measures with the same accuracy level as the RX-5000alpha ±0.03% Brix and ±0.00004nD. The RX-5000i-Plus measures with the same accuracy level as the RX-5000alpha-Plus ±0.010% Brix and ±0.00002nD. The RX-i series come with newly added functions, such as USB flash drive and self-diagnosis capability. These products come standard with a 2 year warranty. The warranty period can be extended to 3 years if the product is registered with ATAGO. FDA 21 CFR Part 11 Software Included in Standard Delivery

Modes:

• Displays the measurement value once the sample reaches the target temperature
• Measures refractive index and temperature at fixed intervals and displays the estimated measurement value at the target temperature
• The thermo-module can be turned off. Without temperature control, the measurement value is displayed in 4 seconds after the START key is pressed
• Displays the measurement value once a certain level of sample stability is achieved.
• Only on the RX-5000i-Plus: Measuring of Low Brix Liquid Samples (such as teas), obtaining highly repeatable results (0.010% Brix).
