Atago RX-5000i automatic digital refractometer

The Atago RX-5000i is an automatic digital refractometer for the measurement of refractive index, Brix and various liquid concentrations. The RX-5000i has a measurement accuracy level of Brix ±0.03% and refractive index ±0.00004, and offers the additional convenience of touch-screen navigation and USB port. There are also four levels of access control, the ability to add user-defined scales and the ability to recall the last 500 measurements.

The RX-5000i offers the user four measurement modes so users have the flexibility to choose the style most suited to their sample.

Mode-1 displays the measurement value once the sample reaches the target temperature. The key advantage of this is maximum accuracy.

Mode-2 measures refractive index and temperature at fixed intervals and displays the estimated measurement value at the target temperature. The advantage of this is fast results.

Mode-S is suitable for emulsion samples and displays the measurement value once a certain level of sample stability has been achieved. Mode-3 provides an option to turn the thermo-module off.

Without temperature control, the measurement value is displayed in 4 s after the ‘start’ key has been pressed.
