Our refractometer / handheld refractometer determines the percentage of N-methyl-2-pyrrolidone in aqueous media with a measurement range of 0 to 100%. The measurement result and the temperature of the sample are shown on the LCD display of the digital refractometer in two lines. Our refractometer / handheld refractometer can quickly and accurately measure various parameters such as percent and refractive index with only four to five drops of the sample. The areas of application of the digital refractometer are very wide-ranging: for water analysis, in the chemical industry or in the manufacture of products such as solvents that may contain N-methyl-2-pyrrolidone.
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.
