Because Pure Water Should Never Be a Mystery. 


 
 At PurePro®, we believe in transparency — not just in water clarity, but in water quality. That’s why every PurePro® AW-400X Ultra-Pure RO+DI System comes with a professional-grade TDS-3000 digital meter. It’s not just an accessory. It’s your front-line water verification tool — simple, powerful, and essential for daily confidence.

 What is the TDS-3000? 

  
The TDS-3000 is a high-precision Total Dissolved Solids (TDS) meter that instantly displays the purity level of your water in parts per million (ppm). It ensures your RO (Reverse Osmosis) and DI (Deionization) filters are doing their job, giving you real-time assurance that your water is ultra-pure — from the source to the rinse.

 How It Works With the AW-400X System:

Pre-Filtration Testing: Use the meter to check your tap water’s initial TDS level and see what you’re starting with.

Post-RO Testing: Verify how much your RO membrane has reduced impurities.

Final Output Testing: Confirm the DI stage brings water down to near 0 TDS, meaning it’s spot-free and safe for rinsing or drinking.
