AutoAqua Titanium S3 TDS-300S – Digital Inline TDS Meter for RO/DI Systems

Titanium S3 – Triple Probe Inline TDS Meter for Full RO/DI System Monitoring (TDS-300S)

The top of the Titanium range. Three probes, three T-fittings, one compact magnetic display — everything you need to keep tabs on every stage of your RO/DI system at once. Drop one probe on your source water, one after the RO membrane, and one after the DI resin, then cycle through all three readings with a press of the button. No more guessing which stage is underperforming or pulling probes in and out to test different points. If you're serious about your water quality, this is the meter to have.

💧 Key Features

• Three Remote Probes – Monitor source water, post-membrane, and post-DI resin simultaneously with three independent titanium probes on separate cables
• Cycle Through All Three Readings – Press the button once per probe to step through each reading on the same display
• Integrated Magnetic Mount – Display snaps onto the metal frame of most RO/DI systems without any brackets or tools
• Titanium Probes – All three probes use corrosion-resistant titanium for reliable long-term performance in continuous water contact
• Inline Installation – Each probe mounts into your ¼" RO/DI line via its own included push-connect T-fitting (three included)
• Calibratable – Each probe can be calibrated independently for accurate readings
• Auto Power-Off – Shuts off automatically after 3 minutes to preserve battery life
• Long Battery Life – Runs on a standard CR2032 lithium battery lasting approximately 1 year
• Low Battery Indicator – Warns you before your readings are compromised
