The RX-9000α 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, meeting demands for high accuracy measurements.

The RX-9000α has a built-in Peltier thermo module for maintaining a constant sample temperature while taking measurements. Manual calibration is also possible to adjust to standard liquid values and to correct differences in measurement values between instruments.
This product comes standard with a two (2) year limited warranty against manufacturer’s defects from the date of the original purchase. The warranty period can be extended to three (3) years if the product is registered with ATAGO.

Mode MODE-1:
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 turn 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.
