Aquarex™ - Poolside Readings, Simple and Accurate

Pool Water Tester, Digital pH Meter, TDS Meter, Water Quality Tester for Spa

• One device instead of seven test strips: pH, ORP, conductivity, TDS, salt, specific gravity, and temperature in a single reading
• Check your levels from your phone: the companion app puts every reading in your hand, right at the water's edge
• Read it even at night: the backlit LCD stays clear in low light
• Adjusts as conditions change: auto temperature compensation keeps readings accurate across a wide range of water temperatures
• Slips into a pocket or pool bag: the compact, lightweight build goes anywhere you test

Stop guessing whether your pool or spa water is balanced and get a real number instead. This water quality tester runs seven readings — pH, ORP, conductivity, TDS, salt level, specific gravity, and temperature — from one compact probe, and a backlit LCD keeps every figure readable even after dark. It pairs with a mobile app for iOS and Android, so you are not squinting at a tiny screen poolside to catch the numbers.

Used on its own it works as a straightforward ph tester or a full conductivity meter, and auto temperature compensation means readings stay accurate whether the water is warm from the sun or cold first thing in the morning. As a pool tester it replaces a fistful of test strips, doubles as a dedicated water ph tester and orp meter for sanitizer balance, and functions as a genuine salinity tester for saltwater pools and spas.
