Digital Refractometer for Seawater Analysis – HI96822

The HI96822 is a rugged, portable digital refractometer designed for the measurement of salinity of natural or artificial seawater. The HI96822 displays results in three popular measurement units: Practical Salinity Units (PSU), salinity in parts per thousands (ppt) and specific gravity (S.G. (20/20)). 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 within 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.

Description

The HI96822 Digital Refractometer eliminates the uncertainty associated with mechanical refractometers by measuring the refractive index to determine the salinity of natural and artificial seawater including brackish, ocean water or saltwater aquarium. The instrument converts the refractive index of a sample to PSU, ppt and specific gravity. These conversions are based on respected scientific publications using the physical properties of seawater (not sodium chloride). The HI96822 is an easy to use tool for measuring salinity in natural and artificial seawater whether in the field, lab or at home.
