ATAGO (Aituo) seawater salinometer PR-100SA adopts the principle of conductivity method, The design of funnel-shaped prism groove is suitable for salinity measurement of seawater, brine and mariculture, with less sample amount (only about 10ml), automatic temperature compensation (ATC), simple operation, fast measurement, and stable placement on the table. Compared with traditional titration, it does not need reagents, reduces pollution, meets the requirements of environmental protection, and is a professional salinometer with high cost performance.
