The Hofun meter combines a titanium-alloy probe with selectable display units for salinity (ppm, ppt, %), while also reporting pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature. Its broad ranges and simple MODE button make it suitable for everything from seawater and koi ponds to RO\/DI systems and household pools.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I read salinity accurately across different units?\u003c\/h3\u003e\n\u003cp\u003eThe Hofun meter cycles between three salinity displays—ppm, ppt and percent—so you can view results in the unit you need without manual conversion. When concentration exceeds the ppm display limit the device automatically switches to ppt; for food-grade checks you can select the percent readout.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePool salt: 0–9,999 ppm range for common pool concentrations.\u003c\/li\u003e\n  \u003cli\u003eSeawater: 10–200 ppt range, with auto-switch from ppm to ppt above 9,999 ppm.\u003c\/li\u003e\n  \u003cli\u003eFood testing: 0.01–25% for brines and preservation solutions.\u003c\/li\u003e\n  \u003cli\u003eOne MODE button to toggle salinity displays quickly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat accuracy and build features ensure reliable TDS and EC readings?\u003c\/h3\u003e\n\u003cp\u003eThe meter uses a corrosion-resistant titanium alloy probe that provides fast, stable contact with the test sample and reduces electrode degradation.
