- Wide usage digital water quality tester: a PH meter and multi-parameter tester designed to improve water quality across applications such as drinking water quality testing, swimming pool quality monitoring, RO/DI system balance, aquariums, spas, hot tubs, wine brewing, and hydroponics. - Three display designs for salinity testing: ppm, ppt, and percent. Swimming pool salt test range: 0-9999 ppm. Seawater test range: 10-200 ppt (1 ppt = 1000 ppm). When the ppm figure exceeds 9999, the meter automatically switches to ppt. Food test range: 0.01-25%. - Easy operation for salinity testing: to use the pool salt tester, simply turn the meter on and press the MODE button to switch to the SALINITY function. This design provides a simple, convenient user experience. Wide application salinity meter is suitable for swimming pools, koi ponds, seawater, aquariums and marine monitoring. - Reliable TDS meter with accurate and quick measurement: the digital pool water tester is equipped with a premium quality titanium alloy probe, enabling fast and precise water quality testing. The device supports 0-9999 ppm and 0-200 ppt ranges for its salinity-related measurements. - Multiplier parameter water test meter with five functions: Salinity, TDS, EC, pH, and Temperature are integrated into one handheld meter. This combination meets diverse water testing needs, saving time and money and serving as a comprehensive water quality test kit. - Practical use scenarios: - Regular home water quality checks: monitor drinking water quality and ensure safe, balanced parameters. - Pool and aquarium maintenance: test pool salinity, pond or seawater salinity, and monitor water quality for fish and corals. - Food and hydroponics testing: measure salinity or sugar content in wine brewing or hydroponic nutrient solutions, using the 0.01-25% range for precise readings. - Build and performance notes: handheld, portable design with a titanium alloy probe for longevity and quick measurements. The meter supports multiple units and ranges to cover common testing needs, providing accurate results across different water types.
