The extended gravity contact time allows the carbon to adsorb a broader range of organic compounds than rapid-flow pitcher filters

HI96822 Digital Seawater Refractometer | Salinity & Specific Gravity | Hanna water quality testing ORP Accuracy: ±1 mVThe 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
