• HI96821 refractometer measures the refractive index of liquid solution samples and converts it to the sodium chloride content of the sample. Designed for the food industry, not suitable for seawater salinity measurement.

• Refractive index measurement is very simple and fast. The user only needs to calibrate the refractometer with distilled or deionized water, then place two drops of the sample onto the sample chamber, and within a few seconds the sodium chloride measurement value of the sample is obtained. The instrument automatically performs temperature compensation, ensuring accurate and reliable measurement results.

• The instrument uses internationally recognized reference unit conversion and temperature compensation methods, and can display NaCl concentration in 4 different reference units: g/100g, g/100  mL, specific gravity, and °Baumé.

• The second line of the LCD screen can simultaneously display the measurement temperature, low battery indicator icon, and other help information.
