Digtal Refractometer Model RX-007a (alpha)

Digtal Refractometer
Model RX-007a (alpha)

The RX-007a (alpha) replaces the conventional Atago's DD-7. Unlike the DD-7 which was a differential refractometer, the RX-700a is equipped with the same type of sample stage as our conventional RX- models. This sample stage allows easy measurements by placing the sample on the stage and pressing the START key.

The RX-007 is suitable for measuring water solutions of very low concentrations (5.000% or less) at a very high accuracy (±0.005%). Samples ideal for measuring will include teas (green tea, black tea, oolong tea) as well as other low concentration sugar beverages.

Other features of the RX-007a include

The RX-007a is recommended for the following applications

A built-in Peltier thermo-module maintains a constant measuring temperature, which eliminates the need for an external water-bath
Measurement starts automatically after the sample reaches the targeted temperature
30 user programmable scales are available
The built-in Flash memory stores the last 30 measurement values which can be viewed, printed or exported to a computer.
A graphic limit bas is displayed when upper and lower values are set.

Wide variety of teas and coffees
Sugar-free and low sugar beverges (Diet becerages)
Extracts of Chinese herbal medicines
Non-alcoholic beer and cocktails
Low concentration water solutions

Measurement Modes	[MODE 1] This is the standard and most accurate mode of measurement. The sample's temperature is adjusted to a set target temperature before measrument is taken. [MODE 2] In this mode, the unit starts measuring immediately after the START key is pressed. The measurement value will be displayed after 20 seconds. This time delay can be manually adjusted. In this mode, the thermo-module can be switched on or off freely.
