Stop guessing whether your pool water is balanced
Check pool and spa water chemistry in seconds — seven readings from one probe, Bluetooth app history and alerts, automatic temperature compensation, without strips or color charts.
Why is this water quality monitor perfect for you
✔ Seven measurements in one dip: Check acidity, oxidation potential, conductivity, dissolved minerals, salt concentration, density, and temperature with a single probe. One handheld meter replaces the need to juggle multiple tools or test strips.
✔ Bluetooth app tracking and alerts: Connect to the free iOS or Android app to view live readings, save past tests, and graph changes over time. Push notifications alert when readings move outside safe zones.
✔ Clear readings in changing temperatures: Automatic temperature compensation adjusts results as water warms or cools. The backlit LCD is easy to read in bright sun or low light, without deciphering color charts or faint markings.
