HANNA – HI96821

Digital Refractometer for Measuring Sodium Chloride in Food

The HI96821 is a rugged, portable digital refractometer designed for sodium chloride (NaCl) measurement. The HI96821 displays NaCl concentration four different ways: g/100 g, g/100 mL, specific gravity, and °Baume. The instrument’s high accuracy and simple operation gives reliable results each and every time. All readings are automatically compensated for temperature variations and displayed with a 1.5 second response time. The sealed flint glass prism and stainless steel well are easy to clean. Just wipe with a soft cloth in preparation for the next sample.


Sample size as small as 2 metric drops (100 μl)


Sealed stainless steel well with high-grade optical prism made of flint glass


Fast 1.5 second response time for temperature compensated readings
