Catch water imbalances before they go unnoticed
Check seven water parameters at once — instant readings, Bluetooth app history and alerts, without test strips or separate instruments.
Why Is This Water Tester Perfect for You?
✔ Seven measurements in one device: Measure pH, temperature, conductivity, total dissolved solids, salinity, oxidation-reduction potential, and specific gravity with one compact tester. Track key water readings without relying on multiple instruments or chemical test strips.
✔ Bluetooth app with alerts and history: Connect to the mobile app to view current readings and measurement history. Alerts for values outside the normal range help identify changes so water can be adjusted promptly.
✔ Portable design with a backlit display: The compact 3.35-ounce tester has a backlit LCD and integrated sensor. Automatic temperature compensation and readings within seconds make routine water checks straightforward.
