Cole-Parmer Atago 4210 ES-421 Palette-style digital refractometer, 0.0 to 10.0% salinity
Fast and accurate concentration readings make these compact portable refractometers ideal for on-site use. A built-in thermistor provides automatic temperature compensation (ATC) so you dont have to struggle with temperature correction tables. Error messages indicate concentrations or temperatures that fall out of range, inadequate sample volume, standardization errors, or low-battery. Easily calibrate units using distilled water and the zero-adjustment button.
