ATAGO RX-7000α Automatic Digital Refractometer

The RX-7000α (alpha) is an improved (upgraded) model for a measurement range of refractive index and measurement temperature of an RX-5000α (alpha). The thermo module for constant temperature is equipped.
It is best for measuring oils and fats of high melt point, higher refractive index perfumes, organic solvents, etc. The RX-7000α (alpha) has the manual calibration facility which compensate difference in standard liquids and measurement values by other refractometers.
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.

Output terminals • Printer (for ATAGO digital printers)
• Computer - RS-232C
Connection to a USB port requires a USB to RS-232 adapter (optional)
Warranty 2 years standard (3 years with product registration)
