Hofun 5-in-1 Digital Water Tester — Salinity (PPM/PPT/%), pH, EC, TDS & Temperature for Aquarium, Pool, Hot Tub — High Accuracy

Compact multiparameter tester from Hofun that combines five essential measurements in one handheld device: Salinity, TDS, EC, pH and Temperature. A titanium alloy probe delivers fast, reliable readings so you can monitor water quality with confidence. Salinity display options and ranges: three display formats (PPM + PPT + %) let you read results in the units you need. Swimming pool salt: 0-9999ppm; Seawater: 10-200ppt (1ppt=1000ppm — when the ppm reading exceeds 9999ppm the meter automatically switches to ppt). Food concentration range: 0.01-25%. TDS and conductivity coverage: broad measurement capability with 0-9999ppm & 0-200ppt ranges to suit multiple testing scenarios. The unit’s five functions — Salinity + TDS + EC + pH + Temperature — are integrated to save space and reduce the need for multiple instruments. Simple operation: power the meter ON and press the MODE button to select SALINITY or cycle through other functions. The user-friendly controls make salt and pH testing quick and convenient. Versatile applications: ideal for drinking water quality checks, swimming pool monitoring, pH balancing in RO/DI systems, aquariums, spas, hot tubs, hydroponics, Koi ponds, seawater and marine aquarium monitoring. Why choose this Hofun tester: accurate, fast measurements from a durable titanium alloy probe, multiple unit displays to avoid manual conversions, and a compact all-in-one design that saves time and money for home and hobby water quality management.
