The Apera Salt20 (AI214) is a compact handheld salinity tester designed for measuring dissolved salt concentration in water and nutrient solutions. Its Brush-resistant Platinum Black (BPB) electrode helps minimize polarization and measurement drift. Automatic temperature compensation, a floating IP67-rated body, and simultaneous salinity and temperature display make it suitable for routine water-quality checks.
