Digital refractometer RDBS1-ATC is designed for fast and accurate determination of salinity of aqueous solution refractive index – in degrees Brix or RI (refractive index nD).
Refractometer is able to measure also the sample or ambient temperature (both in the degrees Celsius °C and in degrees Fahrenheit °F).

Scale Scale range Resolution
Brix 0 to 45 °Bx 0.1 °Bx
Salinity 0 to 28 % 0.1
Refractive index 1.3330 to 1.4100 0.0003
Sample or ambient temperature 0 to 40 °C (32 - 104 °F) 0.5 °C (1 °F)

Example 1: if you measure value 25 °Bx it means that in the 100 g of aqueous solution is dissolved 25 g of sucrose. In other words, in 100 g of aqueous sucrose solution is 25 g of sucrose and 75 g of water. That is why is sometimes used the percent sign (%) as a unit because the sucrose content is a sucrose percentage by weight.

Example 2: If there is dissolved 100 grams of salt in 1 kilogramme of aqueous solution, the salinity of this solution is 10 %.

Tip: use our calculator for calculation of sugar content in aqueous solution

Brackish water 0.5 to 30 ‰
Saline water 30 to 50 ‰
Brine > 50 ‰

The measurement

The liquids measuring is very easy. By holding down the button "READ" for 2 seconds we choose a measuring scale. Place a few drops of the measured liquid on the cleaned sensor, press once the button "READ" and the result value will be showed on the display.
