The RX-5000a (alpha) is an automatic digital refractometer which can set measurement temperature internally and has the following features for measuring the refractive index, Brix or concentration of various liquids accurately and speedily.

-The RX-5000a has a thermo-module to control temperature so a constant temperature water bath is not necessary.
-The measurement starts automatically after the sample reaches your targeted temperature.
-The refractive index and Brix at your targeted temperature are displayed quickly.
-High Brix +-0.03% and refractive index +-0.00004 accuracy can be obtained.
-The RX-5000a displays the top and bottom limit bar for your set control range.
-Measurement adjustments can be made to correlate readings with standard liquid or other refractometer readings.
-60 different user scales can be input according to your sample
-Capable of calling up the last 30 measurements for quick reference.

The NEW RX-5000a-Bev is a re-designed version of the conventional RX-5000a. A flat sample stage makes it easier to wipe off the sample and allows for faster and easier clean up. The RX-5000a -Bev is ideal for measuring beverages and is equipped with all the standard features of the RX-5000a.

The RX-7000a (alpha) is a modified version of the highly accurate RX5000a (alpha) model and features wider measurement ranges for refractive index (up to nD 1.7000) and temperature (up to 70degrees C). The Rx7000a (alpha) is best for measuring samples that have a higher melting point (oils and fats) and/or samples with a higher refractive index (perfumes, organic solvents, etc.)

The RX-9000a is a fully automatic digital refractometer with the highest level of accuracy of its kind. Designed with a wide measurement range, measurement temperature range, and highest measurement accuracy, this instrument is suitable for multiple sample types; such as measuring oils and fats with high melting points, aroma oils of high refractive index and organic solvents.

The NEW RX-007a (alpha) is suitable for measuring water soluble samples with very low concentrations (5.00% or less) such as tea (green tea, black tea, oolong tea) and low sugar beverages at a very high accuracy of +-0.005%

The Brix, Inverted sugar or High Fructose Corn Syrup concentration can be measured in a range of 0.00 to 95.00% and with a high accuracy of +-0.05%! Also, the SMART-1 has Automatic Temperature Compensation function!
-Brix
-Inverted sugar concentration
-HFCS-55 (High Fructose Corn Syrup)
-HFCS-42 High Fructose Corn Syrup)
