About This

- 4-in-1 multifunctionality: Our digital water quality testers measures TDS (total dissolved solids), EC (electrical conductivity), and temperature (°C/°F). This intuitive portable digital water tester for drinking water detects multiple key parameters, making it easy for every household to monitor water safety.
- Easy and fast operation: just turn on the TDS meter and gently stir the water, the stable reading will automatically lock on the LCD within seconds, if there is no operation for more than 2 minutes, the tds ppm meter will automatically turn off
- Multi-Purpose Tds Tester: Tests the purity of drinking water to ensure it is safe and healthy, monitors whether reverse osmosis (RO)/deionization (DI) systems are working properly and need to change filters, maintains aquariums, hydroponics (tests nutrients), wells, swimming pools, hot tubs, spas and tests tap water, bottled water, and more
- Dual-backlit LCD screen：Engineered with a premium dual-backlit LCD screen, our water hardness test outperforms standard digital water testers, delivering superior nighttime visibility and effortless data reading. The intuitive color-coded system provides instant water safety feedback: 🔴Red backlight (40+ ppm) = Non-potable water warning 🟢Green backlight (<40 ppm) = Safe for direct drinking
- Extended Battery Life：Powered by a standard 3V coin cell battery (user-replaceable), our tester lasts 2x longer than traditional 1.5V models. The smart auto-shutoff feature conserves power by turning off the device after 2 minutes of inactivity.
