This Bluetooth 4-in-1 portable water tester simultaneously detects pH, TDS, EC conductivity and water temperature to meet full daily water monitoring demands. It covers 0.00–14.00 pH, 0–9999ppm TDS, 0–9990μS/cm EC and 0–60℃ temperature, with built-in ATC automatic temperature compensation to eliminate temperature-caused reading drift, delivering stable precise data with 0.01 high pH resolution.

Equipped with Bluetooth connection, it syncs real-time data to dedicated mobile APP for historical record storage, trend curve analysis and data export. The backlit LCD screen supports data hold function for convenient value recording, paired with simple one-key calibration for beginners.

Lightweight pen-shaped design supports portable on-site testing. Widely applied to drinking water, fish tanks, hydroponic planting, swimming pools and aquaculture, it is an all-in-one cost-effective tool for long-term water quality tracking.
