Keeping pool or spa water safe and balanced starts with knowing what is in it. This compact tester reads seven essential parameters, shows them on a backlit display for instant on-site readings, and sends real-time data and alerts to your phone through the iOS and Android app. Auto temperature compensation keeps the readings consistent as the temperature changes.
Use it as a digital pH meter, pH tester, TDS tester and ORP meter in one, a swimming pool tester that also suits spas and aquaculture. It runs on 3 x 1.5V LR44 batteries, measures 7.4 x 1.5 x 1.5 in (18.8 x 3.8 x 3.8 cm) and weighs 0.21 lb (0.1 kg). Keep children and non-swimmers away from the water's edge while you test, and never leave a child unattended near a pool or spa.
