The AutoAqua Digital Inline TDS Titanium One is a compact single-point inline meter that measures Total Dissolved Solids (TDS) in real time, letting you know at a glance when it's time to replace your RO/DI filters. Probe: titanium, resists corrosion, connects via a 1/4in push-connect union tee for inline installation Display: backlit LCD, single-button operation Power: CR2032 lithium battery, auto-off after 3 minutes, low-battery indicator, ~1 year battery life Range: 0-999 ppm, 1 ppm resolution, ±2% accuracy Calibration: factory-tested, with a manual calibration option Includes: Titanium One inline TDS meter, CR2032 battery, 1/4in push-connect union tee.Installing this inline (rather than testing water manually with a handheld meter) means you get a continuous readout right at your RO/DI line — useful for catching a spent filter before it lets dissolved solids through into your top-off or mixing water.
