Digital Pool Water Tester for pH and Chlorine

Smart digital 7-in-1 water quality tester with mobile app support

A compact electronic tool for measuring pool or spa water status. This 7-in-1 tester provides real-time values for pH, temperature, conductivity, TDS, salinity, ORP, and specific gravity to help maintain balanced water each day.

Real-time combined water analysis

The integrated sensor tracks seven core parameters within one device. These include water temperature, pH, ORP (oxidation-reduction potential), EC (electrical conductivity), TDS (total dissolved solids), salt levels, and specific gravity. Suitable for residential pools, spas, or aquaculture.

Connect to the mobile app for remote updates

Pair the tester with your smartphone using the free mobile app (iOS and Android supported). The app shows real-time readings, past records, and alerts when values are outside safe limits. Supports remote tracking and quicker adjustments without manual test strips.

Digital LCD display for accurate readings

A backlit LCD provides immediate viewing. Automatic temperature compensation maintains accuracy as conditions change. During use, only the probe is placed in the water. The compact form supports carrying and routine testing throughout the season.

Field-ready and straightforward to operate

Powered by three LR44 batteries, the tester is intended for extended field use. The interface is straightforward, and readings stabilize quickly. Its low weight and protective body allow storage in toolkits or poolside boxes.
