Our refractometer / handheld refractometer determines the percentage of sodium hydroxide in aqueous media with a measurement range of 0 to 55%. The measurement result and the temperature of the sample are shown on the LCD display of the digital refractometer in two lines. The refractometer/handheld refractometer can quickly and accurately measure various parameters and the refractive index with only four to five drops of the sample. The digital refractometer has a wide range of applications: for water analysis, in the chemical industry or in the manufacture of products containing sodium hydroxide.
The funnel-shaped stainless steel ring protects the glass prism from damage in which the liquid sample to be measured is inserted. The internal light source allows measurement in low light conditions. Our refractometer / handheld refractometer is delivered in a sturdy plastic case with pipette and charging cable.
