Atago Hand-held Refractometer – MASTER-S/Mill M

The Atago MASTER-S/Mill-M is used to measures the salinity and specific gravity of seawater, and utilizes a new material that is durable against salty samples, The salinity of seawater is displayed in parts per mill (‰). This refractometer has a scale for measuring the sea water salinity per-mill (ppt or parts per thousand) and water density of seawater. By simple operation the user can obtain a direct reading quickly of the salts concentration and specific gravity of seawater. Sample types include: seawater, artificial seawater, and salt waters.
